Raeann read
19 of the story book. If she had read another 54 pages, she would have read
49 of the whole story book altogether. How many pages were there in the story book?
|
Read |
Not read |
Total |
Before |
1x1 = 1 u |
8x1 = 8 u |
9x1 = 9 u |
Change |
+ 54 |
- 54 |
|
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 Raeann would have read
= 4 u - 1 u
= 3 u
3 u = 54
1 u = 54 ÷ 3 = 18
Number of pages in the story book
= 9 u
= 9 x 18
= 162
Answer(s): 162
