| Before |
5x2 =
10 u |
4x1 =
4 u |
| Change |
- 3x2 =
- 6 u |
- 3x1 =
- 3 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Kylie
and Julie in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Kylie had in the end is repeated. Make the amount that Kylie had in the end the same. LCM of 4 and 2 is 4.
Amount that Kylie had more than Julie
= 10 u - 4 u
= 6 u
6 u = 300
1 u = 300 ÷ 6 = 50
Amount that Julie had at first
= 4 u
= 4 x 50
= $200
Answer(s): $200
