## When Xiao Fang read a story book, he read 13 pages of the whole book on the first day and 10 pages on the second day. At this time, the ratio of the number of pages he read to the number of pages he did not read is 2:3. What page should he read on the third day?

The total pages of the storybook are: 10 △ 22 + 3-13, = 10 △ 115, = 150 (pages), 150 × 22 + 3 + 1 = 61 (pages)

## Xiao Ming read a story book. On the first day, he read a quarter of the whole book. On the second day, he read two more pages than on the first day How many pages is the book?

One quarter plus one quarter equals one half, that is to say, one half of the total number of pages in the previous two days is more than two pages, leaving 20 pages
It's 20 plus 2 divided by 1 minus half, which is 44 pages
