Jenson, Mark, Dylan and Ryan shared $780. Ryan received ¹₁₂ of the total amount of money received by Jenson, Mark and Dylan. Jenson received ⁴₅ of the total amount for Mark and Dylan. Mark received ¹₃ as much money as Dylan. If Dylan gave all his money to Ryan, how much did Ryan have more than Mark in the end?

Jenson	Mark	Dylan	Ryan	Total
12x3			1x3	13x3
4x4	5x4
	1x5	3x5
16 u	5 u	15 u	3 u	39 u

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

The total amount that Jenson, Mark and Dylan have is repeated.  Make the total amount of Jenson, Mark and Dylan the same. LCM of 36 and 12 is 36.

Total amount that Jenson, Mark, Dylan and Ryan shared = 39 u

39 u = 780

1 u = 780 ÷ 39 = 20

	Jenson	Mark	Dylan	Ryan
Before	16 u	5 u	15 u	3 u
Change			- 15 u	+ 15 u
After	16 u	5 u	0 u	18 u

Amount that Ryan had if Dylan gave him all his money
= 3 u + 15 u
= 18 u

Amount that Ryan had more than Mark
= 18 u - 5 u
= 13 u
= 13 x 20
= $260

Answer(s): $260
