Comparing Yoko
and Yen at first |
$116 more |
|
| Before |
5x2 =
10 u |
6x1 =
6 u |
| Change |
- 3x2 =
- 6 u |
- 5x1 =
- 5 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Yoko
and Yen in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Yoko had in the end is repeated. Make the amount that Yoko had in the end the same. LCM of 4 and 2 is 4.
Amount that Yen had less than Yoko
= 10 u - 6 u
= 4 u
4 u = 116
1 u = 116 ÷ 4 = 29
Amount that Yoko had at first
= 10 u
= 10 x 29
= $290
Answer(s): $290
