The remaining pages were:72 pages- 2 × 2/9 = 72 pages-1/3 = 66 pages. This was because Little Ming had read two-ninths of the page on the first day, which was 24 pages. The next day, he read a third of the book, which was 12 pages. Therefore, the remaining pages were the total number of pages minus the number of pages that had been read, which was 72 pages- 24 pages + 12 pages = 66 pages.
