Caden and Flynn gave away the same number of erasers. Caden gave away
34 of his erasers while Flynn gave
59 of his erasers away. Given that Caden had 14 erasers less than Flynn at first, how many erasers did Caden have at first?

Caden |
Flynn |
| Before |
4x5 =
20 u |
9x3 =
27 u |
| Change |
- 3x5 =
- 15 u |
- 5x3 =
- 15 u |
| After |
1x5 =
5 u |
4x3 =
12 u |
The number of erasers that Caden and Flynn gave away is the same. Make the number of erasers that Caden and Flynn gave away the same. LCM of 3 and 5 is 15.
Number of erasers that Caden had at first = 20 u
Number of erasers that Flynn had at first = 27 u
Number of erasers that Caden had less than Flynn at first
= 27 u - 20 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of erasers that Caden had at first
= 20 u
= 20 x 2
= 40
Answer(s): 40
