Total |
| Before |
3x9 =
27 u |
5x9 =
45 u |
8x9 =
72 u |
| Change |
+ 5 u |
- 5 u |
|
| After |
4x8 =
32 u |
5x8 =
40 u |
9x8 =
72 u |
The total number of buttons that Will and Caden had at first and in the end remains unchanged. Make the total number of buttons the same. LCM of 8 and 9 is 72.
Number of buttons that Caden gave Will
= 32 u - 27 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Number of buttons that Will had at first
= 27 u
= 27 x 6
= 162
Answer(s): 162
