12 Reggie'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 Oscar, Jeremy and Eric paid = 6 u
Amount that Oscar and Jeremy paid
= 6 u - 4 u
= 2 u
The amount that Oscar and Jeremy each paid is the same.
Amount that Oscar and Jeremy each paid
= 2 u ÷ 2
= 1 u
Cost of the present = 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Jeremy paid
= 1 u
= 1 x 10
= $10
Answer(s): $10
