Cathy read
19 of the novel. If she had read another 940 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 |
8x7 = 56 u |
9x7 = 63 u |
Change |
+ 940 |
- 940 |
|
After |
6x9 = 54 u |
1x9 = 9 u |
7x9 = 63 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 9 and 7 is 63.
Number of additional pages that Cathy would have read
= 54 u - 7 u
= 47 u
47 u = 940
1 u = 940 ÷ 47 = 20
Number of pages in the novel
= 63 u
= 63 x 20
= 1260
Answer(s): 1260
