Wendy used
34 of her white stickers and
25 of her gold stickers to decorate her diary. In the end, she had an equal number of white stickers and gold stickers left. Given that Wendy had a total of 34 white and gold stickers at first, how many gold stickers did she use to decorate the diary?

White stickers |
Gold stickers |
| Before |
4x3 =
12 u |
5x1 =
5 u |
| Change |
- 3x3 =
- 9 u |
- 2x1 =
- 2 u |
| After |
1x3 =
3 u |
3x1 =
3 u |
The number of white stickers and gold stickers in the end is the same. Make the number of white stickers and gold stickers in the end the same. LCM of 1 and 3 is 3.
Total number of stickers that Wendy used to decorate the diary
= 12 u + 5 u
= 17 u
17 u = 34
1 u = 34 ÷ 17 = 2
Number of gold stickers that Wendy used to decorate the diary
= 2 u
= 2 x 2
= 4
Answer(s): 4
