Caden and Dylan gave away the same number of stamps. Caden gave away
35 of his stamps while Dylan gave
59 of his stamps away. Given that Caden had 18 stamps less than Dylan at first, how many stamps did Caden have at first?

Caden |
Dylan |
Before |
5x5 = 25 u |
9x3 = 27 u |
Change |
- 3x5 = - 15 u |
- 5x3 = - 15 u |
After |
2x5 = 10 u |
4x3 = 12 u |
The number of stamps that Caden and Dylan gave away is the same. Make the number of stamps that Caden and Dylan gave away the same. LCM of 3 and 5 is 15.
Number of stamps that Caden had at first = 25 u
Number of stamps that Dylan had at first = 27 u
Number of stamps that Caden had less than Dylan at first
= 27 u - 25 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of stamps that Caden had at first
= 25 u
= 25 x 9
= 225
Answer(s): 225
