9x1 = 9 u |
2x5 = 10 u |
1 u |
Change |
- 4x1 = - 4 u |
- 1x5 = - 5 u |
|
After |
5x1 = 5 u |
1x5 = 5 u |

Fraction of money that Nora had left
= 1 -
49 =
59 Fraction of money that Jen had left
= 1 -
12 =
12 The amount that Jen and Nora had left is the same. Make the amount that Jen and Nora had left is the same. LCM of 5 and 1 is 5.
Amount that Nora had at first = 9 u
Amount that Jen had at first = 10 u
Amount that Jen had more than Nora at first
= 10 u - 9 u
= 1 u
= $20
Amount that Nora had at first
= 9 u
= 9 x 20
= $180
