Nora read
37 of the book. If she had read another 116 pages, she would have read
89 of the whole book altogether. How many pages were there in the book?
|
Read |
Not read |
Total |
Before |
3x9 = 27 u |
4x9 = 36 u |
7x9 = 63 u |
Change |
+ 116 |
- 116 |
|
After |
8x7 = 56 u |
1x7 = 7 u |
9x7 = 63 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 7 and 9 is 63.
Number of additional pages that Nora would have read
= 56 u - 27 u
= 29 u
29 u = 116
1 u = 116 ÷ 29 = 4
Number of pages in the book
= 63 u
= 63 x 4
= 252
Answer(s): 252
