1x3 =

The number of stickers that Emily had at first and in the end remains unchanged. Make the number of stickers that Emily had the same. LCM of 15 and 5 is 15.
Number of stickers that Emily had more than Shannon at first
= 15 u - 5 u
= 10 u
10 u = 120
1 u = 120 ÷ 10 = 12
Number of stickers that Shannon had at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
