12 Fraction of money that Julie had left
= 1 -
35 =
25 The amount that Julie and Xandra had left is the same. Make the amount that Julie and Xandra had left is the same. LCM of 1 and 2 is 2.
Amount that Xandra had at first = 2 u
Amount that Julie had at first = 5 u
Amount that Julie had more than Xandra at first
= 5 u - 2 u
= 1 u
= $21
Amount that Xandra had at first
= 2 u
= 2 x 21
= $42
