- 1x4 =
- 4 u |
- 1x7 =
- 7 u |
After

6x4 =
24 u |
3x7 =
21 u |
The number of books that Michael and Jeremy each had at first is the same. Make the number of books that Michael and Jeremy had at first the same. LCM of 7 and 4 is 28.
Number of books that Jeremy donated more than Michael
= 7 u - 4 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of books that Jeremy had
= 28 u
= 28 x 9
= 252
Answer(s): 252
