9x4 =
36 u |
4x9 =
36 u |
Change

- 1x4 =
- 4 u |
- 1x9 =
- 9 u |
After
|
8x4 =
32 u |
3x9 =
27 u |
The number of books that Japheth and Liam each had at first is the same. Make the number of books that Japheth and Liam had at first the same. LCM of 9 and 4 is 36.
Number of books that Liam donated more than Japheth
= 9 u - 4 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of books that Liam had
= 36 u
= 36 x 10
= 360
Answer(s): 360
