Primary school fourth grade key mathematics questions and answers
The following are some of the key math questions and answer types in the first volume of the fourth grade: ** I. Type of application questions ** 1. ** Problem on operational relationships ** - [Question: Xiao Ming has 25 candies. Xiao Hong has 3 times more candies than Xiao Ming. How many candies does Xiao Hong have?] - [Answer: First calculate the number of Little Red's candies by three times, which is 25×3 = 75 candies. Adding the extra 5 candies, 75+5 = 80 candies, so Little Red has 80 candies.] 2. ** About how to convert units in application questions ** - [Question: The capacity of a water tank is 500 liters, and 5000 milliliters of water can be used every day. How many days can this water be used?] - Answer: First, convert the units. Since 1 liter = 1000 milliliters, 500 liters = 500×1000 = 500000 milliliters. Divide the total amount of water by the daily water consumption. 500,000/5,000 = 100 days. ** 2.

Because the quality of the remaining goods in the six boxes is equal to the quality of the goods in the original two boxes, the goods taken away are equivalent to the original $6 - 2=4$boxes. The weight of each box of goods was: $36/4 = 9$(tons). ** 2. Question on the area of the graph ** 1. ** Title * If two squares of the same size overlap, each square has a side length of 27 centimeters. After one side of the overlapping part is covered, there is 15 centimeters left.

Xiao Qiang ate a small piece every 30 minutes and ate the last small cube at 18:00. He begged them to start eating the first small piece. 2. ** Answer ** 18:00 - 14:40 = 3 hours and 20 minutes = 3×60 + 20 = 200 minutes. The number of pieces eaten = $200/(30 - 20)=20$, Little Ming ate 20 yuan, and the time taken was 20×20 = 400 minutes = 6 hours and 40 minutes. The time to start eating the first piece was 14:40 - 6:40 = 8:00. ** 6.

He asked A and B how many minutes they had set for self-study every day. 2. ** Answer ** Self-study time after reducing half an hour every day = $1/(6 - 1)=1/5$hour = 12 minutes. The original plan was to study on his own every day = $30 + 12 = 42$minutes. A's original plan was to study by himself every day = $12×6 - 30 = 42$minutes. ** 8.
