25 Harry's share : Total share = 2 : 5
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 5 and 7 is 35.
Amount that Elijah, Ivan and Oscar paid = 25 u
Amount that Elijah and Ivan paid
= 25 u - 7 u
= 18 u
The amount that Elijah and Ivan each paid is the same.
Amount that Elijah and Ivan each paid
= 18 u ÷ 2
= 9 u
Cost of the gift = 35 u
35 u = 140
1 u = 140 ÷ 35 = 4
Amount that Ivan paid
= 9 u
= 9 x 4
= $36
Answer(s): $36
