| Before |
9 u |
4 u |
| Change |

- 1 u |
| After |
|
3 u |
Comparing Zara
and Fiona in the end |
3x3 =
9 u |
1x3 =
3 u |
The number of stickers that Zara had at first and in the end remains unchanged. Make the number of stickers that Zara had the same. LCM of 9 and 3 is 9.
Number of stickers that Zara had more than Fiona at first
= 9 u - 4 u
= 5 u
5 u = 70
1 u = 70 ÷ 5 = 14
Number of stickers that Fiona had at first
= 4 u
= 4 x 14
= 56
Answer(s): 56
