- 1 u |
| After |
|
3 u |
Comparing Hazel
and Min in the end |
4x3 =
12 u |
1x3 =
3 u |
The number of cards that Hazel had at first and in the end remains unchanged. Make the number of cards that Hazel had the same. LCM of 12 and 4 is 12.
Number of cards that Hazel had more than Min at first
= 12 u - 4 u
= 8 u
8 u = 80
1 u = 80 ÷ 8 = 10
Number of cards that Min had at first
= 4 u
= 4 x 10
= 40
Answer(s): 40
