Will had ³₄ as many stickers as Luis. Luis had ⁴₇ as many stickers as Roshel. After Will and Roshel gave 4 stickers to Luis, Luis had thrice as many stickers as Will. Roshel then had the same number of stickers as Luis.

1. What was the ratio of the number of stickers Roshel had to the number of stickers Will had in the beginning? Answer in simplest form.
2. How many stickers did Luis have in the end?

Will	Luis	Roshel
3	4
	4	7
3	4	7

(a)
The number of stickers that Luis is repeated.  

Ratio of the number of stickers that Roshel had to the number of stickers that Will had in the beginning = 7 : 3

	Will	Luis	Roshel	Total
Before	3x1 = 3 u	4x1 = 4 u	7x1 = 7 u	14x1 = 14 u
Change	- 4	+ 8	- 4
After	1x2 = 2 u	3x2 = 6 u	3x2 = 6 u	7x2 = 14 u

The total number of stickers at first and in the end remains unchanged. Make the total number of stickers the same. LCM of 14 and 7 is 14.

Number of stickers that Luis received from Will and Roshel
= 2 x 4
= 8

Number of stickers that Luis received from Will and Roshel
= 2 x 1 u
= 2 u

2 u = 4

1 u = 4 ÷ 2 = 2

Number of stickers that Ashley had in the end
= 6 u
= 6 x 2
= 12
