Esther read
13 of the novel. If she had read another 154 pages, she would have read
67 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x7 = 7 u |
2x7 = 14 u |
3x7 = 21 u |
Change |
+ 154 |
- 154 |
|
After |
6x3 = 18 u |
1x3 = 3 u |
7x3 = 21 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 3 and 7 is 21.
Number of additional pages that Esther would have read
= 18 u - 7 u
= 11 u
11 u = 154
1 u = 154 ÷ 11 = 14
Number of pages in the novel
= 21 u
= 21 x 14
= 294
Answer(s): 294
