Raeann and Julie collected seashells. Raeann gave 30% of her seashells to Julie and as a result, Julie's seashells increased by 25%. If Raeann had 63 seashells left, find the number of seashells Julie should give to Raeann in the end so that both had an equal number of seashells.

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

7 u = 63

1 u = 63 ÷ 7 = 9

Number of seashells that Julie had more than Raeann in the end
= 15 u - 7 u
= 8 u

Number of seashells that Julie should give to Raeann so that both had an equal number of seashells in the end
= 8 u ÷ 2
= 4 u
= 4 x 9
= 36

Answer(s): 36
