12 Warren's share : Total share = 1 : 2
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 13 and 3 is 39.
Amount that Fred, Ahmad and David paid = 26 u
Amount that Fred and Ahmad paid
= 26 u - 12 u
= 14 u
The amount that Fred and Ahmad each paid is the same.
Amount that Fred and Ahmad each paid
= 14 u ÷ 2
= 7 u
Cost of the gift = 39 u
39 u = 156
1 u = 156 ÷ 39 = 4
Amount that Ahmad paid
= 7 u
= 7 x 4
= $28
Answer(s): $28
