Fraction of money that Sarah had left
= 1 -
35 =
25 Fraction of money that Min had left
= 1 -
23 =
13 The amount that Min and Sarah had left is the same. Make the amount that Min and Sarah had left is the same. LCM of 2 and 1 is 2.
Amount that Sarah had at first = 5 u
Amount that Min had at first = 6 u
Amount that Min had more than Sarah at first
= 6 u - 5 u
= 1 u
= $27
Amount that Sarah had at first
= 5 u
= 5 x 27
= $135
Answer(s): $135
