12 Fraction of money that Usha had left
= 1 -
35 =
25 The amount that Usha and Gem had left is the same. Make the amount that Usha and Gem had left is the same. LCM of 1 and 2 is 2.
Amount that Gem had at first = 2 u
Amount that Usha had at first = 5 u
Amount that Usha had more than Gem at first
= 5 u - 2 u
= 1 u
= $18
Amount that Gem had at first
= 2 u
= 2 x 18
= $36
