25 =
35 Fraction of money that Roshel had left
= 1 -
12 =
12 The amount that Roshel and Irene had left is the same. Make the amount that Roshel and Irene had left is the same. LCM of 3 and 1 is 3.
Amount that Irene had at first = 5 u
Amount that Roshel had at first = 6 u
Amount that Roshel had more than Irene at first
= 6 u - 5 u
= 1 u
= $29
Amount that Irene had at first
= 5 u
= 5 x 29
= $145
