Zoe used ³₅ of her yellow stickers and ²₇ of her silver stickers to decorate her diary. In the end, she had an equal number of yellow stickers and silver stickers left. Given that Zoe had a total of 468 yellow and silver stickers at first, how many silver stickers did she use to decorate the diary?

	Yellow stickers	Silver stickers
Before	5x5 = 25 u	7x2 = 14 u
Change	- 3x5 = - 15 u	- 2x2 = - 4 u
After	2x5 = 10 u	5x2 = 10 u

The number of yellow stickers and silver stickers in the end is the same.  Make the number of yellow stickers and silver stickers in the end the same.  LCM of 2 and 5 is 10.

Total number of stickers that Zoe used to decorate the diary
= 25 u + 14 u
= 39 u

39 u = 468

1 u = 468 ÷ 39 = 12

Number of silver stickers that Zoe used to decorate the diary
= 4 u
= 4 x 12
= 48

Answer(s): 48
