79 =
29 Fraction of money that Hilda had left
= 1 -
45 =
15 The amount that Hilda and Raeann had left is the same. Make the amount that Hilda and Raeann had left is the same. LCM of 2 and 1 is 2.
Amount that Raeann had at first = 9 u
Amount that Hilda had at first = 10 u
Amount that Hilda had more than Raeann at first
= 10 u - 9 u
= 1 u
= $22
Amount that Raeann had at first
= 9 u
= 9 x 22
= $198
