12 =
12 The amount that Min and Irene had left is the same. Make the amount that Min and Irene had left is the same. LCM of 5 and 1 is 5.
Amount that Irene had at first = 9 u
Amount that Min had at first = 10 u
Amount that Min had more than Irene at first
= 10 u - 9 u
= 1 u
= $23
Amount that Irene had at first
= 9 u
= 9 x 23
= $207
