Jade read
37 of the manual. If she had read another 4 pages, she would have read
47 of the whole manual altogether. How many pages were there in the manual?
|
Read |
Not read |
Total |
Before |
3x1 = 3 u |
4x1 = 4 u |
7x1 = 7 u |
Change |
+ 4 |
- 4 |
|
After |
4x1 = 4 u |
3x1 = 3 u |
7x1 = 7 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 7 and 7 is 7.
Number of additional pages that Jade would have read
= 4 u - 3 u
= 1 u
1 u = 4
1 u = 4 ÷ 1 = 4
Number of pages in the manual
= 7 u
= 7 x 4
= 28
Answer(s): 28
