Jack, Gabriel, Eric and Vincent shared $84. Vincent received ¹₆ of the total amount of money received by Jack, Gabriel and Eric. Jack received ⁴₅ of the total amount for Gabriel and Eric. Gabriel received ¹₃ as much money as Eric. If Gabriel gave all his money to Vincent, how much did Vincent have more than Jack in the end?

Jack	Gabriel	Eric	Vincent	Total
6x6			1x6	7x6
4x4	5x4
	1x5	3x5
16 u	5 u	15 u	6 u	42 u

The total amount that Gabriel and Eric have is repeated.  Make the total amount of Gabriel and Eric the same.  LCM of 4 and 5 is 20.

The total amount that Jack, Gabriel and Eric have is repeated.  Make the total amount of Jack, Gabriel and Eric the same. LCM of 36 and 6 is 36.

Total amount that Jack, Gabriel, Eric and Vincent shared = 42 u

42 u = 84

1 u = 84 ÷ 42 = 2

	Jack	Gabriel	Eric	Vincent
Before	16 u	5 u	15 u	6 u
Change		- 5 u		+ 5 u
After	16 u	0 u	15 u	11 u

Amount that Vincent had if Gabriel gave him all his money
= 6 u + 5 u
= 11 u

Amount that Vincent had more than Jack
= 11 u - 16 u
= -5 u
= -5 x 2
= $-10

Answer(s): $-10
