Sabrina read
37 of the manual. If she had read another 2 pages, she would have read
49 of the whole manual altogether. How many pages were there in the manual?
|
Read |
Not read |
Total |
Before |
3x9 = 27 u |
4x9 = 36 u |
7x9 = 63 u |
Change |
+ 2 |
- 2 |
|
After |
4x7 = 28 u |
5x7 = 35 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 Sabrina would have read
= 28 u - 27 u
= 1 u
1 u = 2
1 u = 2 ÷ 1 = 2
Number of pages in the manual
= 63 u
= 63 x 2
= 126
Answer(s): 126
