38 of her stickers, Vanessa had twice as many stickers as Min. How many stickers did Min have at first?

Comparing Vanessa and
Min at first |
12 more |
|
| Before |
10 u |
8 u |
| Change |
|
- 3 u |
| After |
10 u |
5 u |
Comparing Vanessa and
Min in the end |
2x5 =
10 u |
1x5 =
5 u |
Number of stickers that Min had in the end is repeated. Make the number of stickers that Min had in the end the same. LCM of 1 and 5 is 5.
Number of stickers that Vanessa had at first = 10 u
Number of stickers that Vanessa had more than Min at first
= 10 u - 8 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Number of stickers that Min had at first
= 8 u
= 8 x 6
= 48
Answer(s): 48
