Tina used ³₇ of her pink stickers and ²₅ of her silver stickers to decorate her diary. In the end, she had an equal number of pink stickers and silver stickers left. Given that Tina had a total of 328 pink and silver stickers at first, how many silver stickers did she use to decorate the diary?

	Pink stickers	Silver stickers
Before	7x3 = 21 u	5x4 = 20 u
Change	- 3x3 = - 9 u	- 2x4 = - 8 u
After	4x3 = 12 u	3x4 = 12 u

The number of pink stickers and silver stickers in the end is the same.  Make the number of pink stickers and silver stickers in the end the same.  LCM of 4 and 3 is 12.

Total number of stickers that Tina used to decorate the diary
= 21 u + 20 u
= 41 u

41 u = 328

1 u = 328 ÷ 41 = 8

Number of silver stickers that Tina used to decorate the diary
= 8 u
= 8 x 8
= 64

Answer(s): 64
