Min read
12 of the novel. If she had read another -6 pages, she would have read
49 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x9 = 9 u |
1x9 = 9 u |
2x9 = 18 u |
Change |
+ -6 |
- -6 |
|
After |
4x2 = 8 u |
5x2 = 10 u |
9x2 = 18 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 2 and 9 is 18.
Number of additional pages that Min would have read
= 8 u - 9 u
= -1 u
-1 u = -6
1 u = -6 ÷ -1 = 6
Number of pages in the novel
= 18 u
= 18 x 6
= 108
Answer(s): 108
