25 =
35 Fraction of money that Shiyun had left
= 1 -
12 =
12 The amount that Shiyun and Vanessa had left is the same. Make the amount that Shiyun and Vanessa had left is the same. LCM of 3 and 1 is 3.
Amount that Vanessa had at first = 5 u
Amount that Shiyun had at first = 6 u
Amount that Shiyun had more than Vanessa at first
= 6 u - 5 u
= 1 u
= $18
Amount that Vanessa had at first
= 5 u
= 5 x 18
= $90
