Fraction of money that Kathy had left
= 1 -
35 =
25 Fraction of money that Shannon had left
= 1 -
23 =
13 The amount that Shannon and Kathy had left is the same. Make the amount that Shannon and Kathy had left is the same. LCM of 2 and 1 is 2.
Amount that Kathy had at first = 5 u
Amount that Shannon had at first = 6 u
Amount that Shannon had more than Kathy at first
= 6 u - 5 u
= 1 u
= $23
Amount that Kathy had at first
= 5 u
= 5 x 23
= $115
Answer(s): $115
