Fraction of money that Hilda had left
= 1 -
12 =
12 Fraction of money that Emily had left
= 1 -
35 =
25 The amount that Emily and Hilda had left is the same. Make the amount that Emily and Hilda had left is the same. LCM of 1 and 2 is 2.
Amount that Hilda had at first = 2 u
Amount that Emily had at first = 5 u
Amount that Emily had more than Hilda at first
= 5 u - 2 u
= 1 u
= $19
Amount that Hilda had at first
= 2 u
= 2 x 19
= $38
