Fraction of money that Anna had left
= 1 -
35 =
25 Fraction of money that Jen had left
= 1 -
23 =
13 The amount that Jen and Anna had left is the same. Make the amount that Jen and Anna had left is the same. LCM of 2 and 1 is 2.
Amount that Anna had at first = 5 u
Amount that Jen had at first = 6 u
Amount that Jen had more than Anna at first
= 6 u - 5 u
= 1 u
= $20
Amount that Anna had at first
= 5 u
= 5 x 20
= $100
Answer(s): $100
