Asher had
38 the number of buttons that Ahmad had at first. After Ahmad gave Asher 34 of his buttons, Asher had
45 the number of buttons that Ahmad had. How many buttons did Ahmad have in the end?

Ahmad |
Total |
Before |
3x9 = 27 u |
8x9 = 72 u |
11x9 = 99 u |
Change |
+ 17 u |
- 17 u |
|
After |
4x11 = 44 u |
5x11 = 55 u |
9x11 = 99 u |
The total number of buttons that Asher and Ahmad had at first and in the end remains unchanged. Make the total number of buttons the same. LCM of 11 and 9 is 99.
Number of buttons that Ahmad gave Asher
= 44 u - 27 u
= 17 u
17 u = 34
1 u = 34 ÷ 17 = 2
Number of buttons that Ahmad had in the end
= 55 u
= 55 x 2
= 110
Answer(s): 110
