25 =
35 Fraction of money that Jane had left
= 1 -

12 The amount that Jane and Anna had left is the same. Make the amount that Jane and Anna had left is the same. LCM of 3 and 1 is 3.
Amount that Anna had at first = 5 u
Amount that Jane had at first = 6 u
Amount that Jane had more than Anna at first
= 6 u - 5 u
= 1 u
= $21
Amount that Anna had at first
= 5 u
= 5 x 21
= $105
