Tiffany read
18 of the novel. If she had read another 36 pages, she would have read
78 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x1 = 1 u |
7x1 = 7 u |
8x1 = 8 u |
Change |
+ 36 |
- 36 |
|
After |
7x1 = 7 u |
1x1 = 1 u |
8x1 = 8 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 8 and 8 is 8.
Number of additional pages that Tiffany would have read
= 7 u - 1 u
= 6 u
6 u = 36
1 u = 36 ÷ 6 = 6
Number of pages in the novel
= 8 u
= 8 x 6
= 48
Answer(s): 48
