Fiona and Elyse had an equal number of stickers at first. Fiona used
15 of her stickers and Elyse used
16 of her stickers. They used 55 stickers altogether. How many stickers did Elyse have in the end?

Fiona |
Elyse |
Before |
5x6 = 30 u |
6x5 = 30 u |
Change |
- 1x6 = - 6 u |
- 1x5 = - 5 u |
After |
4x6 = 24 u |
5x5 = 25 u |
The number of stickers that Fiona and Elyse each had at first is the same. Make the number of stickers that Fiona and Elyse each had at first the same. LCM of 5 and 6 is 30.
Number of stickers that Fiona and Elyse used
= 6 u + 5 u
= 11 u
11 u = 55
1 u = 55 ÷ 11 = 5
Number of stickers that Elyse had in the end
= 25 u
= 25 x 5
= 125
Answer(s): 125
