Ivory and Kimberly collected stickers. Ivory gave 60% of her stickers to Kimberly and as a result, Kimberly's stickers increased by 20%. If Ivory had 22 stickers left, find the number of stickers Kimberly should give to Ivory in the end so that both had an equal number of stickers.

	Ivory	Kimberly	Comparing the change in Kimberly's stickers
Before	5x1 = 5 u		5x3 = 15u
Change	- 3x1 = - 3 u	+ 3x1 = + 3 u	+ 1x3 = + 3 u
After	2x1 = 2 u		6x3 = 18 u

60% = ⁶⁰₁₀₀ = ³₅
20% = ²⁰₁₀₀ = ¹₅

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

2 u = 22

1 u = 22 ÷ 2 = 11

Number of stickers that Kimberly had more than Ivory in the end
= 18 u - 2 u
= 16 u

Number of stickers that Kimberly should give to Ivory so that both had an equal number of stickers in the end
= 16 u ÷ 2
= 8 u
= 8 x 11
= 88

Answer(s): 88
