Elyse read
29 of the book. If she had read another 145 pages, she would have read
58 of the whole book altogether. How many pages were there in the book?

Total |
| Before |
2x8 =
16 u |
7x8 =
56 u |
9x8 =
72 u |
| Change |
+ 145 |
- 145 |
|
| After |
5x9 =
45 u |
3x9 =
27 u |
8x9 =
72 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 9 and 8 is 72.
Number of additional pages that Elyse would have read
= 45 u - 16 u
= 29 u
29 u = 145
1 u = 145 ÷ 29 = 5
Number of pages in the book
= 72 u
= 72 x 5
= 360
Answer(s): 360
