Total |
| Before |
3x9 =
27 u |
5x9 =
45 u |
8x9 =
72 u |
| Change |
+ 5 u |
- 5 u |
|
| After |
4x8 =
32 u |
5x8 =
40 u |
9x8 =
72 u |
The total number of stickers that Julian and Wesley had at first and in the end remains unchanged. Make the total number of stickers the same. LCM of 8 and 9 is 72.
Number of stickers that Wesley gave Julian
= 32 u - 27 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of stickers that Julian had at first
= 27 u
= 27 x 3
= 81
Answer(s): 81
