Shiyun and Jaslyn collected stickers. Shiyun gave 50% of her stickers to Jaslyn and as a result, Jaslyn's stickers increased by 30%. If Shiyun had 33 stickers left, find the number of stickers Jaslyn should give to Shiyun in the end so that both had an equal number of stickers.

	Shiyun	Jaslyn	Comparing the change in Jaslyn's stickers
Before	2x3 = 6 u		10x1 = 10u
Change	- 1x3 = - 3 u	+ 1x3 = + 3 u	+ 3x1 = + 3 u
After	1x3 = 3 u		13x1 = 13 u

50% = ⁵⁰₁₀₀ = ¹₂
30% = ³⁰₁₀₀ = ³₁₀

The increase in the number of stickers that Jaslyn had is repeated.  Make the increase in the number of stickers that Jaslyn had the same. LCM of 1 and 3 = 3

3 u = 33

1 u = 33 ÷ 3 = 11

Number of stickers that Jaslyn had more than Shiyun in the end
= 13 u - 3 u
= 10 u

Number of stickers that Jaslyn should give to Shiyun so that both had an equal number of stickers in the end
= 10 u ÷ 2
= 5 u
= 5 x 11
= 55

Answer(s): 55
