Anna had 36 more stickers than Kylie. After Kylie gave away
16 of her stickers, Anna had twice as many stickers as Kylie. How many stickers did Kylie have at first?

Comparing Anna and
Kylie at first |
36 more |
|
| Before |
10 u |
6 u |
| Change |
|
- 1 u |
| After |
10 u |
5 u |
Comparing Anna and
Kylie in the end |
2x5 =
10 u |
1x5 =
5 u |
Number of stickers that Kylie had in the end is repeated. Make the number of stickers that Kylie had in the end the same. LCM of 1 and 5 is 5.
Number of stickers that Anna had at first = 10 u
Number of stickers that Anna had more than Kylie at first
= 10 u - 6 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of stickers that Kylie had at first
= 6 u
= 6 x 9
= 54
Answer(s): 54
