Ivan, Cody, Asher and Ethan shared $56. Ethan received ²₅ of the total amount of money received by Ivan, Cody and Asher. Ivan received ¹₃ of the total amount for Cody and Asher. Cody received ²₃ as much money as Asher. If Cody gave all his money to Ethan, how much did Ethan have more than Ivan in the end?

Ivan	Cody	Asher	Ethan	Total
5x4			2x4	7x4
1x5	3x5
	2x3	3x3
5 u	6 u	9 u	8 u	28 u

The total amount that Cody and Asher have is repeated.  Make the total amount of Cody and Asher the same.  LCM of 5 and 3 is 15.

The total amount that Ivan, Cody and Asher have is repeated.  Make the total amount of Ivan, Cody and Asher the same. LCM of 20 and 5 is 20.

Total amount that Ivan, Cody, Asher and Ethan shared = 28 u

28 u = 56

1 u = 56 ÷ 28 = 2

	Ivan	Cody	Asher	Ethan
Before	5 u	6 u	9 u	8 u
Change		- 6 u		+ 6 u
After	5 u	0 u	9 u	14 u

Amount that Ethan had if Cody gave him all his money
= 8 u + 6 u
= 14 u

Amount that Ethan had more than Ivan
= 14 u - 5 u
= 9 u
= 9 x 2
= $18

Answer(s): $18
