12 Zeph's share : Total share = 1 : 2
The total amount paid for the present is repeated. Make the total amount the same. LCM of 5 and 3 is 15.
Amount that Lee, Billy and Bobby paid = 10 u
Amount that Lee and Billy paid
= 10 u - 6 u
= 4 u
The amount that Lee and Billy each paid is the same.
Amount that Lee and Billy each paid
= 4 u ÷ 2
= 2 u
Cost of the present = 15 u
15 u = 45
1 u = 45 ÷ 15 = 3
Amount that Billy paid
= 2 u
= 2 x 3
= $6
Answer(s): $6
