How many pages has Xiaohua read try not to use equations .

5 7 of the number of pages read equals 5 2 times the number of pages not read, and divide by 5 2, i.e. 5 7 (5 2) = 2 7

2 7 indicates the number of pages read, which means the number of pages that have not been read.

That is, the number of pages not read is equal to 2 7 of the number of pages read

The total number of pages is equal to 9 7 reads

That is, the number of pages read is equal to 7 9 of the total number of pages

Therefore: the number of pages read = 252 7 9 = 196 the number of pages unread = 252-196 = 56

Solution: 5 7 (5 2) = 2 7 Answer:

The problem is equal to the 1 7 that has been read = 1 2 that has not been read, that is, 2 times the read = 7 times the unread, that is to say, the read 2 = (252 - read) 7, and the deformation is the read 9 = 252 * 7; Thus the number of pages he has read is 252 * 7 9 = 196 pages.

5 7 of the number of pages read equals 5 2 of the number of pages not read

The ratio of the number of pages read to the number of pages not read is: 5 2:5 7=7:2, then the number of pages read accounts for the total number of pages: 7 (7+2).

The number of pages read is: 252 7 (7+2)=196 pages.

Answer: Page 196 read.

A: On this day, Xiaohua read 9 pages.

Let the viewed page be x, then.

x+3x=x+10+2(x+10)

4x=3x+30

x = 30 Total pages of the book = x + 3x = 120

Solution: Let the whole book be x pages, and read 2 5x pages.

1-2/5)x=60

3/5x=60

x=60÷3/5

x=60×5/3

x=1002/5x=100×2/5=40

A: Xiaohua read 40 pages.

Arithmetic: 60 (1-2 5) 2 5=60 3 5 2 5

40 (pages) Answer: Xiaohua read 40 pages.

If the whole book is x pages, then I read 2 5 x pages.

x-2/5 x=60

Solution x=100

2/5x=40

Looked at 40 pages.

1-5/2)x=60

x=100 Xiaohua looked at x*5 2=40 pages.
