25 =
35 Fraction of money that Betty had left
= 1 -
12 =
12 The amount that Betty and Yen had left is the same. Make the amount that Betty and Yen had left is the same. LCM of 3 and 1 is 3.
Amount that Yen had at first = 5 u
Amount that Betty had at first = 6 u
Amount that Betty had more than Yen at first
= 6 u - 5 u
= 1 u
= $22
Amount that Yen had at first
= 5 u
= 5 x 22
= $110
