79 =
29 Fraction of money that Jane had left
= 1 -
45 =
15 The amount that Jane and Joelle had left is the same. Make the amount that Jane and Joelle had left is the same. LCM of 2 and 1 is 2.
Amount that Joelle had at first = 9 u
Amount that Jane had at first = 10 u
Amount that Jane had more than Joelle at first
= 10 u - 9 u
= 1 u
= $29
Amount that Joelle had at first
= 9 u
= 9 x 29
= $261
Answer(s): $261
