At first, Natalie had an equal number of yellow and blue stickers . She gave away ³₅ of her yellow stickers and some blue stickers. In the end, she was left with ²₃ of her stickers. What fraction of the blue stickers did Natalie give away?

	Yellow	Blue	Total
Comparing yellow stickers and blue stickers at first	1x5x3 = 15 u	1x5x3 =  15 u	2x5x3 =  30 u
Before	5x3 = 15 u	15 u	3x10 = 30 u
Change	- 3x3 = - 9 u	- 1 u	- 2x10 = - 10 u
After	2x3 = 6 u	14 u	1x10 = 20 u

After2_x3 =
6 u
14 u1_x10 =
20 u
The number of yellow stickers at first is repeated. Make the number of yellow stickers the first the same. LCM of 5 and 1 is 5.

The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 10 and 3 is 30.

Number of blue stickers that Natalie was left with
= 20 u - 6 u
= 14 u

Number of blue stickers that Natalie gave away
= 15 u - 14 u
= 1 u

Fraction of the blue stickers that Natalie gave away = ¹₁₅

Answer(s): ¹₁₅
