Comparing Emma
and Raeann at first |
$60 more |
|
| Before |
7x2 =
14 u |
3x3 =
9 u |
| Change |
- 4x2 =
- 8 u |
- 2x3 =
- 6 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Emma
and Raeann in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Emma had in the end is repeated. Make the amount that Emma had in the end the same. LCM of 2 and 3 is 6.
Amount that Emma had more than Raeann
= 14 u - 9 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Amount that Raeann had at first
= 9 u
= 9 x 12
= $108
Answer(s): $108
