Raeann and Jane collected stamps. Raeann gave 60% of her stamps to Jane and as a result, Jane's stamps increased by 20%. If Raeann had 16 stamps left, find the number of stamps Jane should give to Raeann in the end so that both had an equal number of stamps.

	Raeann	Jane	Comparing the change in Jane's stamps
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 stamps that Jane had is repeated.  Make the increase in the number of stamps that Jane had the same. LCM of 3 and 1 = 3

2 u = 16

1 u = 16 ÷ 2 = 8

Number of stamps that Jane had more than Raeann in the end
= 18 u - 2 u
= 16 u

Number of stamps that Jane should give to Raeann so that both had an equal number of stamps in the end
= 16 u ÷ 2
= 8 u
= 8 x 8
= 64

Answer(s): 64
