12 Fraction of money that Yen had left
= 1 -
35 =
25 The amount that Yen and Fanny had left is the same. Make the amount that Yen and Fanny had left is the same. LCM of 1 and 2 is 2.
Amount that Fanny had at first = 2 u
Amount that Yen had at first = 5 u
Amount that Yen had more than Fanny at first
= 5 u - 2 u
= 1 u
= $20
Amount that Fanny had at first
= 2 u
= 2 x 20
= $40
