Fabian had
25 the number of stickers that Perry had at first. After Perry gave Fabian 60 of his stickers, Fabian had
47 the number of stickers that Perry had. How many stickers did Fabian have at first?

Fabian |
Perry |
Total |
Before |
2x11 = 22 u |
5x11 = 55 u |
7x11 = 77 u |
Change |
+ 6 u |
- 6 u |
|
After |
4x7 = 28 u |
7x7 = 49 u |
11x7 = 77 u |
The total number of stickers that Fabian and Perry had at first and in the end remains unchanged. Make the total number of stickers the same. LCM of 7 and 11 is 77.
Number of stickers that Perry gave Fabian
= 28 u - 22 u
= 6 u
6 u = 60
1 u = 60 ÷ 6 = 10
Number of stickers that Fabian had at first
= 22 u
= 22 x 10
= 220
Answer(s): 220
