Jean and Kylie collected stickers. Jean gave 60% of her stickers to Kylie and as a result, Kylie's stickers increased by 20%. If Jean had 14 stickers left, find the number of stickers Kylie should give to Jean in the end so that both had an equal number of stickers.

	Jean	Kylie	Comparing the change in Kylie'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 Kylie had is repeated.  Make the increase in the number of stickers that Kylie had the same. LCM of 3 and 1 = 3

2 u = 14

1 u = 14 ÷ 2 = 7

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

Number of stickers that Kylie should give to Jean so that both had an equal number of stickers in the end
= 16 u ÷ 2
= 8 u
= 8 x 7
= 56

Answer(s): 56
