Oliver, Tommy, Fred and Glen shared $420. Glen received ¹₄ of the total amount of money received by Oliver, Tommy and Fred. Oliver received ³₅ of the total amount for Tommy and Fred. Tommy received ¹₂ as much money as Fred. If Tommy gave all his money to Glen, how much did Glen have more than Oliver in the end?

Oliver	Tommy	Fred	Glen	Total
4x6			1x6	5x6
3x3	5x3
	1x5	2x5
9 u	5 u	10 u	6 u	30 u

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

The total amount that Oliver, Tommy and Fred have is repeated.  Make the total amount of Oliver, Tommy and Fred the same. LCM of 24 and 4 is 24.

Total amount that Oliver, Tommy, Fred and Glen shared = 30 u

30 u = 420

1 u = 420 ÷ 30 = 14

	Oliver	Tommy	Fred	Glen
Before	9 u	5 u	10 u	6 u
Change		- 5 u		+ 5 u
After	9 u	0 u	10 u	11 u

Amount that Glen had if Tommy gave him all his money
= 6 u + 5 u
= 11 u

Amount that Glen had more than Oliver
= 11 u - 9 u
= 2 u
= 2 x 14
= $28

Answer(s): $28
