Elijah and Pierre gave away the same number of buttons. Elijah gave away
35 of his buttons while Pierre gave
59 of his buttons away. Given that Elijah had 24 buttons less than Pierre at first, how many buttons did Elijah have at first?

Pierre |
Before |
5x5 = 25 u |
9x3 = 27 u |
Change |
- 3x5 = - 15 u |
- 5x3 = - 15 u |
After |
2x5 = 10 u |
4x3 = 12 u |
The number of buttons that Elijah and Pierre gave away is the same. Make the number of buttons that Elijah and Pierre gave away the same. LCM of 3 and 5 is 15.
Number of buttons that Elijah had at first = 25 u
Number of buttons that Pierre had at first = 27 u
Number of buttons that Elijah had less than Pierre at first
= 27 u - 25 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of buttons that Elijah had at first
= 25 u
= 25 x 12
= 300
Answer(s): 300
