12 Fraction of money that Lucy had left
= 1 -
35 =
25 The amount that Lucy and Pamela had left is the same. Make the amount that Lucy and Pamela had left is the same. LCM of 1 and 2 is 2.
Amount that Pamela had at first = 2 u
Amount that Lucy had at first = 5 u
Amount that Lucy had more than Pamela at first
= 5 u - 2 u
= 1 u
= $26
Amount that Pamela had at first
= 2 u
= 2 x 26
= $52
