Ten Techniques of Fraction Reduction
The technique of fraction reduction was as follows: 1. First reduce, then general division method: When calculating the addition and substitution of different decimators, you can first decompose each fraction's numerator and decimator into a factor, and then carry out subsequent calculations after reducing. 2. The grouping general fraction method: According to the characteristics of the fraction, the grouping general fraction method is used to simplify the calculation. 3. Item-by-item general division method. 4. Separation fraction method: Separates the fraction reasonably to simplify it. 5. The method of splitting items. 6. [Whole general division, and then simplify: For the addition and deduction of a fraction and an integral expression, the whole general division can be simplified to solve the problem.] 7. Sequential addition, general fraction, and calculation: When multiple general fraction in the fraction addition operation is troublesome, observe the characteristics of the decimal, add them from left to right, and then divide them in order to simplify the calculation. 8. Split-term elimination method: If the difference between the two factors in the fraction's numerator is 1, the split-term addition method can be used to calculate. 9. Reciprocal evaluation, global substitution: When the fraction structure presents certain characteristics, it can be solved by calculating the reciprocals and global substitution. 10. In some cases, it would be easier to simplify the false fraction into the form of the sum of the whole fraction and the true fraction. "Prosperous Brocade Record" is equally exciting.

The Basic Methods of Fraction Reduction
The basic method of fraction reduction was as follows: 1. * * Factoring **: To find the parts that can be reduced by decomposing the numerator and numerator. For example, using the complete square difference formula [a 2 - 2ab + b 2 =(a-b) 2] and the square deviation formula [a 2-b 2 =(a + b)(a-b)] to decompose. 2. * * Reduction **: Reduce the same factor in the numerator and numerator to simplify the fraction. 3. * * General Fraction **: For addition and substitution of a fraction with different predictors, the simplest common numerator must be found, and the fraction must be converted into a fraction with the same numerator before the operation. 4. * * Calculating according to the order of operations **: Calculating according to the order of multiplication and division, then addition and addition. If there are any parenthesis, calculate the formula in the parenthesis first. 5. * * Special Skill **: - * * Reduce first, then calculate **: When calculating the addition and substitution of different decimators, you can first decompose the numerator and the decimal of each fraction into factors, and then calculate after reducing. - * * Whole General Fraction **: For the addition and deduction of a fraction and an integral expression, the whole general fraction method can be used to simplify. - * * Sequential addition, successive general fraction **: When there are many fraction in the fraction addition operation, if you add them from left to right and divide them in turn, the calculation can be simplified. - * * Split-term Elimination Method **: If the difference between the two factors in the decimal of the fraction is 1, you can use a specific formula to calculate the split-term addition method. - * * Inverse evaluation, whole substitution **: For some evaluation problems, you can first find the value of the inverse of the fraction, and then get the value of the original formula. - * * Separation fraction method **: To simplify a fraction by splitting it into the sum or difference of several fraction. - * * Set unit 1 **: If the total amount of work or the total distance is not specified in the distance problem or the engineering problem, you can set it as a unit of 1 to simplify the calculation.

The 8 Basic Steps of Fraction Reduction
The following are the basic steps for fraction reduction: 1. [Factoring: Factoring the numerator and numerator of a quotient. This will help you find the common factor to reduce the number of factors.] 2. Dealing with negative exponents: If there are negative exponents, according to the calculation rules of negative exponents, the negative sign of the exponents represents the reciprocals, and it is converted into the form of positive exponents. 3. Observe the order of operations: first multiply, then multiply and divide, then add and subtract. If there are parenthesis, calculate the ones in the parenthesis first. 4. Dealing with the operation of the fraction and the whole expression: Treat the whole expression as a fraction structure with a quotient of 1, and then perform the operation according to the law. 5. Division to multiplication: If there is a division operation, it must be converted into a multiplication operation, which is to multiply the numerator and numerator of the division by the division. 6. Reduction: Find the common factor of the numerator and the decimal to reduce the fraction into the simplest form. However, you must pay attention to judging the fraction before the reduction. You cannot judge the relevant properties of the fraction after the reduction. 7. Combining similar terms: For similar terms in the fraction, such as similar terms in the numerator and numerator or similar terms in the parenthesis, they are combined and simplified. 8. Checking the Denominator: Make sure that the Denominator in the process of reduction is not 0, and at the same time, make sure that the original fraction and the fraction that appears in the process of reduction are meaningful during the final substitution evaluation.

Funny fraction stories: Share some interesting fraction stories.
Once, there was a pizza divided into 8 slices. Tom ate 3 slices. So he ate 3/8 of the pizza. His sister was so hungry that she ate the remaining 5 slices, which is 5/8 of the pizza. It was a simple yet funny fraction story about sharing food.
Formula for fraction and simplicity
There wasn't a single formula for fraction reduction, but it could be summarized as follows: 1. For the case where the numerator and numerator of the fraction had a quotient, the factor decomposition was performed first. This helped to discover the resolvable parts of the numerator and the numerator. 2. Observe the coefficient of each term in the fraction to see if there is a common factor that can be extracted to simplify the fraction. 3. When a fraction had a fraction to add or subtract, the general fraction would first transform it into a fraction with the same numerator before performing the operation. The general fraction was to find the lowest common multiple of each numerator as the numerator after the general fraction. 4. In the process of reduction, one had to pay attention to the order of operations, following the principle of first multiplying and dividing, then adding and deducting. If there were parenthesis, calculate the formula in the parenthesis first. 5. After the reduction was completed, the result was checked to see if it was the simplest fraction, which meant that the numerator and numerator could no longer be reduced.

Reflection on the revision class of fraction multiplication
The following are some key points for reflection on the revision of the fraction multiplication class: ** I. Teaching Method and Students 'Dominant Status ** 1. ** Combination of lecture and practice ** - In the revision class, the combination of teaching and practice helped to bring out the students 'main position. For example, let the students think and complete the questions on their own, then go on stage to answer and explain the methods. If they have any questions, they can communicate freely and finally correct them collectively. In this way, the entire process was communicated, discussed, and explained by the students. The students were highly motivated and proactive, and even students with learning difficulties could actively participate. 2. ** Teamwork ** - Teamwork was also an effective teaching method. In the practice, through the cooperation between the groups, the method of leading the poor students was adopted. In this process, the focus was on cultivating the excellent students 'ability to explain questions, guiding the excellent students to use practical operations to help the students with learning difficulties understand and master the knowledge and skills about fraction multiplication. This would not only help the students with learning difficulties improve, but it would also save time in the classroom and allow the teachers to pay more attention to the students with learning difficulties. However, when designing the questions, one had to take into account the characteristics of the gifted students to avoid wasting their time on simple questions. ** 2. Type of fraction multiplication and calculation points ** 1. ** Multiplying scores by scores ** - Directly using the rules, the product multiplied by the numerator was the numerator of the product, and the product multiplied by the numerator was the numerator of the product. If it could be reduced, it would be reduced first before calculating. When calculating, you should pay attention to the number after the numerator reduction and write it up, and the number after the decimal reduction should be written down. 2. ** Multiplying an integral with a fraction ** - Because any whole number could be regarded as a fraction with a 1 as the Denominator, the calculation method was the same as multiplying a fraction by a fraction. It was also to reduce the fraction before calculating. 3. ** Multiplying Decimals and Fraction ** - If there was a multiple relationship between the decimals and the numbers of the fraction, it could be calculated by reducing the fraction first, or it could be calculated by multiplying the fraction by the fraction. 4. ** Multiplying scores by scores ** - He converted the score into a fake score and then multiplied it by the score. ** 3. Problems and improvements in teaching ** 1. ** Explanation Method of the exercises ** - The traditional practice class was often a repetitive process of doing questions, checking, correcting, explaining, and continuing. It was easy for students to lack a sense of freshness and rhythm. He could try the model of " doing questions, checking, finding errors, explaining, changing, and reflecting ". He could dig out the test points and possible variations behind the exercises, giving the initiative to the students, allowing them to have more time to think deeply, improve their computing power, and reduce their calculation errors. 2. ** Attention to students of different levels ** - In the design of the review class, the needs of students of different levels should be considered. If the overall difficulty of the questions was low, it might make the time of the excellent students insufficient; if the difficulty was too high, it might make it difficult for the students with learning difficulties to keep up. Therefore, the difficulty of the questions should be arranged reasonably so that every student could have a greater harvest in the revision class. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
