0.6 =
35 Fraction of Glen's amount left
= 1 -
35 =
25 0.3 =
310 Fraction of Raeann's amount left
= 1 -
310 =
710 The amount that Glen and Raeann each had in the end is the same. Make the numerators the same. LCM of 2 and 7 is 14.
25 of Glen's amount =
710 of Raeann's amount
1435 of Glen's amount =
1420 of Raeann's amount
Amount that Raeann had less than Glen
= 35 u - 20 u
= 15 u
15 u = 330
1 u = 330 ÷ 15 = 22
Amount that Raeann had at first
= 20 u
= 20 x 22
= $440
Answer(s): $440
