Fraction of money that Jane had left
= 1 -
12 =
12 Fraction of money that Risa had left
= 1 -
35 =
25 The amount that Risa and Jane had left is the same. Make the amount that Risa and Jane had left is the same. LCM of 1 and 2 is 2.
Amount that Jane had at first = 2 u
Amount that Risa had at first = 5 u
Amount that Risa had more than Jane at first
= 5 u - 2 u
= 1 u
= $22
Amount that Jane had at first
= 2 u
= 2 x 22
= $44
Answer(s): $44
