David, Eric, Albert and Bryan shared $252. Bryan received ⁴₅ of the total amount of money received by David, Eric and Albert. David received ¹₃ of the total amount for Eric and Albert. Eric received ²₃ as much money as Albert. If Albert gave all his money to Bryan, how much did Bryan have more than Eric in the end?

David	Eric	Albert	Bryan	Total
5x4			4x4	9x4
1x5	3x5
	2x3	3x3
5 u	6 u	9 u	16 u	36 u

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

The total amount that David, Eric and Albert have is repeated.  Make the total amount of David, Eric and Albert the same. LCM of 20 and 5 is 20.

Total amount that David, Eric, Albert and Bryan shared = 36 u

36 u = 252

1 u = 252 ÷ 36 = 7

	David	Eric	Albert	Bryan
Before	5 u	6 u	9 u	16 u
Change			- 9 u	+ 9 u
After	5 u	6 u	0 u	25 u

Amount that Bryan had if Albert gave him all his money
= 16 u + 9 u
= 25 u

Amount that Bryan had more than Eric
= 25 u - 6 u
= 19 u
= 19 x 7
= $133

Answer(s): $133
