12 Justin's share : Total share = 1 : 2
The total amount paid for the present is repeated. Make the total amount the same. LCM of 9 and 3 is 9.
Amount that Eric, Zane and Zeph paid = 6 u
Amount that Eric and Zane paid
= 6 u - 2 u
= 4 u
The amount that Eric and Zane each paid is the same.
Amount that Eric and Zane each paid
= 4 u ÷ 2
= 2 u
Cost of the present = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Zane paid
= 2 u
= 2 x 10
= $20
Answer(s): $20
