Emma used
23 of her yellow stickers and
35 of her white stickers to decorate her diary. In the end, she had an equal number of yellow stickers and white stickers left. Given that Emma had a total of 88 yellow and white stickers at first, how many white stickers did she use to decorate the diary?

Yellow stickers |
White stickers |
| Before |
3x2 =
6 u |
5x1 =
5 u |
| Change |
- 2x2 =
- 4 u |
- 3x1 =
- 3 u |
| After |
1x2 =
2 u |
2x1 =
2 u |
The number of yellow stickers and white stickers in the end is the same. Make the number of yellow stickers and white stickers in the end the same. LCM of 1 and 2 is 2.
Total number of stickers that Emma used to decorate the diary
= 6 u + 5 u
= 11 u
11 u = 88
1 u = 88 ÷ 11 = 8
Number of white stickers that Emma used to decorate the diary
= 3 u
= 3 x 8
= 24
Answer(s): 24
