Victoria used ²₅ of her silver stickers and ²₇ of her pink stickers to decorate her diary. In the end, she had an equal number of silver stickers and pink stickers left. Given that Victoria had a total of 184 silver and pink stickers at first, how many pink stickers did she use to decorate the diary?

	Silver stickers	Pink stickers
Before	5x5 = 25 u	7x3 = 21 u
Change	- 2x5 = - 10 u	- 2x3 = - 6 u
After	3x5 = 15 u	5x3 = 15 u

The number of silver stickers and pink stickers in the end is the same.  Make the number of silver stickers and pink stickers in the end the same.  LCM of 3 and 5 is 15.

Total number of stickers that Victoria used to decorate the diary
= 25 u + 21 u
= 46 u

46 u = 184

1 u = 184 ÷ 46 = 4

Number of pink stickers that Victoria used to decorate the diary
= 6 u
= 6 x 4
= 24

Answer(s): 24
