Shannon read
18 of the story book. If she had read another 779 pages, she would have read
67 of the whole story book altogether. How many pages were there in the story book?
|
Read |
Not read |
Total |
Before |
1x7 = 7 u |
7x7 = 49 u |
8x7 = 56 u |
Change |
+ 779 |
- 779 |
|
After |
6x8 = 48 u |
1x8 = 8 u |
7x8 = 56 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 8 and 7 is 56.
Number of additional pages that Shannon would have read
= 48 u - 7 u
= 41 u
41 u = 779
1 u = 779 ÷ 41 = 19
Number of pages in the story book
= 56 u
= 56 x 19
= 1064
Answer(s): 1064
