Hilda read
13 of the manual. If she had read another 27 pages, she would have read
56 of the whole manual altogether. How many pages were there in the manual?
|
Read |
Not read |
Total |
Before |
1x2 = 2 u |
2x2 = 4 u |
3x2 = 6 u |
Change |
+ 27 |
- 27 |
|
After |
5x1 = 5 u |
1x1 = 1 u |
6x1 = 6 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 3 and 6 is 6.
Number of additional pages that Hilda would have read
= 5 u - 2 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of pages in the manual
= 6 u
= 6 x 9
= 54
Answer(s): 54
