57 of his stickers while Vincent gave away
35 of his stickers. Given that Fabian gave away 12 stickers more than Vincent, how many stickers did Fabian have at first?

Fabian's stickers |
Vincent's stickers |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
- 5x5 =
- 25 u |
- 3x7 =
- 21 u |
| After |
2x5 =
10 u |
2x7 =
14 u |
The number of cards that Fabian and Vincent each had at first is the same. Make the number of cards that Fabian and Vincent each had at first the same. LCM of 7 and 5 is 35.
Number of stickers that Fabian gave away more than Vincent
= 25 u - 21 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of stickers that Fabian had at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
