Henry, Cody, Oscar and Fred shared $75. Fred received ²₃ of the total amount of money received by Henry, Cody and Oscar. Henry received ¹₄ of the total amount for Cody and Oscar. Cody received ¹₂ as much money as Oscar. If Oscar gave all his money to Fred, how much did Fred have more than Cody in the end?

Henry	Cody	Oscar	Fred	Total
3x5			2x5	5x5
1x3	4x3
	1x4	2x4
3 u	4 u	8 u	10 u	25 u

The total amount that Cody and Oscar have is repeated.  Make the total amount of Cody and Oscar the same.  LCM of 3 and 4 is 12.

The total amount that Henry, Cody and Oscar have is repeated.  Make the total amount of Henry, Cody and Oscar the same. LCM of 15 and 3 is 15.

Total amount that Henry, Cody, Oscar and Fred shared = 25 u

25 u = 75

1 u = 75 ÷ 25 = 3

	Henry	Cody	Oscar	Fred
Before	3 u	4 u	8 u	10 u
Change			- 8 u	+ 8 u
After	3 u	4 u	0 u	18 u

Amount that Fred had if Oscar gave him all his money
= 10 u + 8 u
= 18 u

Amount that Fred had more than Cody
= 18 u - 4 u
= 14 u
= 14 x 3
= $42

Answer(s): $42
