27 of her stickers, Ivory had twice as many stickers as Yoko. How many stickers did Yoko have at first?

Comparing Ivory and
Yoko at first |
24 more |
|
| Before |
10 u |
7 u |
| Change |
|
- 2 u |
| After |
10 u |
5 u |
Comparing Ivory and
Yoko in the end |
2x5 =
10 u |
1x5 =
5 u |
Number of stickers that Yoko had in the end is repeated. Make the number of stickers that Yoko had in the end the same. LCM of 1 and 5 is 5.
Number of stickers that Ivory had at first = 10 u
Number of stickers that Ivory had more than Yoko at first
= 10 u - 7 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of stickers that Yoko had at first
= 7 u
= 7 x 8
= 56
Answer(s): 56
