2x4 =

1x4 =
4 u |
The number of stickers that Betty had at first and in the end remains unchanged. Make the number of stickers that Betty had the same. LCM of 8 and 2 is 8.
Number of stickers that Betty had more than Roshel at first
= 8 u - 5 u
= 3 u
3 u = 96
1 u = 96 ÷ 3 = 32
Number of stickers that Roshel had at first
= 5 u
= 5 x 32
= 160
Answer(s): 160
