12 Howard'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 Jenson, Oscar and Ethan paid = 10 u
Amount that Jenson and Oscar paid
= 10 u - 6 u
= 4 u
The amount that Jenson and Oscar each paid is the same.
Amount that Jenson and Oscar each paid
= 4 u ÷ 2
= 2 u
Cost of the present = 15 u
15 u = 90
1 u = 90 ÷ 15 = 6
Amount that Oscar paid
= 2 u
= 2 x 6
= $12
Answer(s): $12
