Tina read
19 of the novel. If she had read another 51 pages, she would have read
49 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x1 = 1 u |
8x1 = 8 u |
9x1 = 9 u |
Change |
+ 51 |
- 51 |
|
After |
4x1 = 4 u |
5x1 = 5 u |
9x1 = 9 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 9 and 9 is 9.
Number of additional pages that Tina would have read
= 4 u - 1 u
= 3 u
3 u = 51
1 u = 51 ÷ 3 = 17
Number of pages in the novel
= 9 u
= 9 x 17
= 153
Answer(s): 153
