Wendy and Gillian collected stickers. Wendy gave 30% of her stickers to Gillian and as a result, Gillian's stickers increased by 25%. If Wendy had 56 stickers left, find the number of stickers Gillian should give to Wendy in the end so that both had an equal number of stickers.

	Wendy	Gillian	Comparing the change in Gillian's stickers
Before	10x1 = 10 u		4x3 = 12u
Change	- 3x1 = - 3 u	+ 3x1 = + 3 u	+ 1x3 = + 3 u
After	7x1 = 7 u		5x3 = 15 u

30% = ³⁰₁₀₀ = ³₁₀
25% = ²⁵₁₀₀ = ¹₄

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

7 u = 56

1 u = 56 ÷ 7 = 8

Number of stickers that Gillian had more than Wendy in the end
= 15 u - 7 u
= 8 u

Number of stickers that Gillian should give to Wendy so that both had an equal number of stickers in the end
= 8 u ÷ 2
= 4 u
= 4 x 8
= 32

Answer(s): 32
