Comparing Jade
and Ivory at first |
$52 more |
|
| Before |
8x2 =
16 u |
4x3 =
12 u |
| Change |
- 5x2 =
- 10 u |
- 3x3 =
- 9 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Jade
and Ivory in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Jade had in the end is repeated. Make the amount that Jade had in the end the same. LCM of 2 and 3 is 6.
Amount that Jade had more than Ivory
= 16 u - 12 u
= 4 u
4 u = 52
1 u = 52 ÷ 4 = 13
Amount that Ivory had at first
= 12 u
= 12 x 13
= $156
Answer(s): $156
