35 Fraction of money that Tiffany had left
= 1 -
12 =
12 The amount that Tiffany and Raeann had left is the same. Make the amount that Tiffany and Raeann had left is the same. LCM of 3 and 1 is 3.
Amount that Raeann had at first = 5 u
Amount that Tiffany had at first = 6 u
Amount that Tiffany had more than Raeann at first
= 6 u - 5 u
= 1 u
= $21
Amount that Raeann had at first
= 5 u
= 5 x 21
= $105
Answer(s): $105
