Fiona and Hazel had an equal number of stickers at first. Fiona used
12 of her stickers and Hazel used
18 of her stickers. They used 25 stickers altogether. How many stickers did Hazel have in the end?

Fiona |
Hazel |
Before |
2x4 = 8 u |
8x1 = 8 u |
Change |
- 1x4 = - 4 u |
- 1x1 = - 1 u |
After |
1x4 = 4 u |
7x1 = 7 u |
The number of stickers that Fiona and Hazel each had at first is the same. Make the number of stickers that Fiona and Hazel each had at first the same. LCM of 2 and 8 is 8.
Number of stickers that Fiona and Hazel used
= 4 u + 1 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Number of stickers that Hazel had in the end
= 7 u
= 7 x 5
= 35
Answer(s): 35
