| Before |
2x5 =
10 u |
5x2 =
10 u |
| Change |
- 1x5 =
- 5 u |
- 3x2 =
- 6 u |
| After |
1x5 =
5 u |
2x2 =
4 u |
The amount that Sam and Yoko had at first is the same. Make the amount that Sam and Yoko had at first the same. LCM of 2 and 5 is 10.
Amount that Yoko spent more than Sam
= 6 u - 5 u
= 1 u
1 u = 10
Amount that Sam had at first
= 10 u
= 10 x 10
= $100
Answer(s): $100
