2 u |
Comparing Shannon
and Linda in the end |
3x2 =
6 u |
1x2 =
2 u |
The number of stickers that Shannon had at first and in the end remains unchanged. Make the number of stickers that Shannon had the same. LCM of 6 and 3 is 6.
Number of stickers that Shannon had more than Linda at first
= 6 u - 3 u
= 3 u
3 u = 66
1 u = 66 ÷ 3 = 22
Number of stickers that Linda had at first
= 3 u
= 3 x 22
= 66
Answer(s): 66
