At first, Eva had an equal number of silver and gold stickers . She gave away ²₃ of her silver stickers and some gold stickers. In the end, she was left with ²₅ of her stickers. What fraction of the gold stickers did Eva give away?

	Silver	Gold	Total
Comparing silver stickers and gold stickers at first	1x3x5 = 15 u	1x3x5 =  15 u	2x3x5 =  30 u
Before	3x5 = 15 u	15 u	5x6 = 30 u
Change	- 2x5 = - 10 u	- 8 u	- 2x6 = - 18 u
After	1x5 = 5 u	7 u	3x6 = 12 u

After1_x5 =
5 u
7 u3_x6 =
12 u
The number of silver stickers at first is repeated. Make the number of silver stickers the first the same. LCM of 3 and 1 is 3.

The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 6 and 5 is 30.

Number of gold stickers that Eva was left with
= 12 u - 5 u
= 7 u

Number of gold stickers that Eva gave away
= 15 u - 7 u
= 8 u

Fraction of the gold stickers that Eva gave away = ⁸₁₅

Answer(s): ⁸₁₅
