Ahmad had
58 the number of stickers that Warren had at first. After Warren gave Ahmad 35 of his stickers, Ahmad had
45 the number of stickers that Warren had. How many stickers did Warren have in the end?

Ahmad |
Warren |
Total |
Before |
5x9 = 45 u |
8x9 = 72 u |
13x9 = 117 u |
Change |
+ 7 u |
- 7 u |
|
After |
4x13 = 52 u |
5x13 = 65 u |
9x13 = 117 u |
The total number of stickers that Ahmad and Warren had at first and in the end remains unchanged. Make the total number of stickers the same. LCM of 13 and 9 is 117.
Number of stickers that Warren gave Ahmad
= 52 u - 45 u
= 7 u
7 u = 35
1 u = 35 ÷ 7 = 5
Number of stickers that Warren had in the end
= 65 u
= 65 x 5
= 325
Answer(s): 325
