Japheth and Liam gave away the same number of buttons. Japheth gave away
34 of his buttons while Liam gave
49 of his buttons away. Given that Japheth had 11 buttons less than Liam at first, how many buttons did Japheth have at first?

Japheth |
Liam |
Before |
4x4 = 16 u |
9x3 = 27 u |
Change |
- 3x4 = - 12 u |
- 4x3 = - 12 u |
After |
1x4 = 4 u |
5x3 = 15 u |
The number of buttons that Japheth and Liam gave away is the same. Make the number of buttons that Japheth and Liam gave away the same. LCM of 3 and 4 is 12.
Number of buttons that Japheth had at first = 16 u
Number of buttons that Liam had at first = 27 u
Number of buttons that Japheth had less than Liam at first
= 27 u - 16 u
= 11 u
11 u = 11
1 u = 11 ÷ 11 = 1
Number of buttons that Japheth had at first
= 16 u
= 16 x 1
= 16
Answer(s): 16
