At first, Opal had an equal number of yellow and gold stickers . She gave away ²₃ of her yellow stickers and some gold stickers. In the end, she was left with ¹₄ of her stickers. What fraction of the gold stickers did Opal give away?

	Yellow	Gold	Total
Comparing yellow stickers and gold stickers at first	1x3x2 = 6 u	1x3x2 =  6 u	2x3x2 =  12 u
Before	3x2 = 6 u	6 u	4x3 = 12 u
Change	- 2x2 = - 4 u	- 5 u	- 1x3 = - 9 u
After	1x2 = 2 u	1 u	3x3 = 3 u

After1_x2 =
2 u
1 u3_x3 =
3 u
The number of yellow stickers at first is repeated. Make the number of yellow 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 4 is 12.

Number of gold stickers that Opal was left with
= 3 u - 2 u
= 1 u

Number of gold stickers that Opal gave away
= 6 u - 1 u
= 5 u

Fraction of the gold stickers that Opal gave away = ⁵₆

Answer(s): ⁵₆
