- 1x3 =
- 3 u |
- 1x5 =
- 5 u |
After

4x3 =
12 u |
2x5 =
10 u |
The number of books that Charlie and Wesley each had at first is the same. Make the number of books that Charlie and Wesley had at first the same. LCM of 5 and 3 is 15.
Number of books that Wesley donated more than Charlie
= 5 u - 3 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of books that Wesley had
= 15 u
= 15 x 7
= 105
Answer(s): 105
