12 Pierre's share : Total share = 1 : 2
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 9 and 3 is 9.
Amount that Fred, Glen and Ken paid = 6 u
Amount that Fred and Glen paid
= 6 u - 4 u
= 2 u
The amount that Fred and Glen each paid is the same.
Amount that Fred and Glen each paid
= 2 u ÷ 2
= 1 u
Cost of the gift = 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Amount that Glen paid
= 1 u
= 1 x 7
= $7
Answer(s): $7
