35 Fraction of money that Gabby had left
= 1 -
12 =
12 The amount that Gabby and Jaslyn had left is the same. Make the amount that Gabby and Jaslyn had left is the same. LCM of 3 and 1 is 3.
Amount that Jaslyn had at first = 5 u
Amount that Gabby had at first = 6 u
Amount that Gabby had more than Jaslyn at first
= 6 u - 5 u
= 1 u
= $18
Amount that Jaslyn had at first
= 5 u
= 5 x 18
= $90
