25 =
35 Fraction of money that Kylie had left
= 1 -
12 =
12 The amount that Kylie and Shiyun had left is the same. Make the amount that Kylie and Shiyun had left is the same. LCM of 3 and 1 is 3.
Amount that Shiyun had at first = 5 u
Amount that Kylie had at first = 6 u
Amount that Kylie had more than Shiyun at first
= 6 u - 5 u
= 1 u
= $30
Amount that Shiyun had at first
= 5 u
= 5 x 30
= $150
