Before
|
7x4 =
28 u |
4x7 =
28 u |
Change
|
- 1x4 =
- 4 u |
- 1x7 =
- 7 u |
After
|
6x4 =
24 u |
3x7 =
21 u |
The number of books that Neave and Seth each had at first is the same. Make the number of books that Neave and Seth had at first the same. LCM of 7 and 4 is 28.
Number of books that Seth donated more than Neave
= 7 u - 4 u
= 3 u
3 u = 6
1 u = 6 ÷ 3 = 2
Number of books that Seth had
= 28 u
= 28 x 2
= 56
Answer(s): 56
