Comparing Jane
and Ivory at first |
$135 more |
|
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 3x2 =
- 6 u |
- 6x1 =
- 6 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Jane
and Ivory in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Jane had in the end is repeated. Make the amount that Jane had in the end the same. LCM of 4 and 2 is 4.
Amount that Jane had more than Ivory
= 10 u - 7 u
= 3 u
3 u = 135
1 u = 135 ÷ 3 = 45
Amount that Ivory had at first
= 7 u
= 7 x 45
= $315
Answer(s): $315
