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