Before

9x1 =
9 u |
3x3 =
9 u |
Change

- 1x1 =
- 1 u |
- 1x3 =
- 3 u |
After
|
8x1 =
8 u |
2x3 =
6 u |
The number of books that Neave and Simon each had at first is the same. Make the number of books that Neave and Simon had at first the same. LCM of 9 and 3 is 9.
Number of books that Simon donated more than Neave
= 3 u - 1 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Number of books that Simon had
= 9 u
= 9 x 3
= 27
Answer(s): 27
