57 =
27 Fraction of money that Xandra had left
= 1 -
34 =
14 The amount that Xandra and Kylie had left is the same. Make the amount that Xandra and Kylie had left is the same. LCM of 2 and 1 is 2.
Amount that Kylie had at first = 7 u
Amount that Xandra had at first = 8 u
Amount that Xandra had more than Kylie at first
= 8 u - 7 u
= 1 u
= $18
Amount that Kylie had at first
= 7 u
= 7 x 18
= $126
