Raeann read
16 of the novel. If she had read another 144 pages, she would have read
710 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x5 = 5 u |
5x5 = 25 u |
6x5 = 30 u |
Change |
+ 144 |
- 144 |
|
After |
7x3 = 21 u |
3x3 = 9 u |
10x3 = 30 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 6 and 10 is 30.
Number of additional pages that Raeann would have read
= 21 u - 5 u
= 16 u
16 u = 144
1 u = 144 ÷ 16 = 9
Number of pages in the novel
= 30 u
= 30 x 9
= 270
Answer(s): 270
