PSLE At first, Min had an equal number of blue and pink stickers . She gave away
34 of her blue stickers and some pink stickers. In the end, she was left with
14 of her stickers. What fraction of the pink stickers did Min give away?

Total |
Comparing blue stickers and pink stickers at first |
1x4x1 = 4 u |
1x4x1 = 4 u |
2x4x1 = 8 u |
Before |
4x1 = 4 u |
4 u |
4x2 = 8 u |
Change |
- 3x1 = - 3 u |
- 3 u |
- 1x2 = - 6 u |
After |
1x1 = 1 u |
1 u |
3x2 = 2 u |
After
1x1 =
1 u1 u
3x2 =
2 uThe number of blue stickers at first is repeated. Make the number of blue stickers the first the same. LCM of 4 and 1 is 4.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 8 and 4 is 8.
Number of pink stickers that Min was left with
= 2 u - 1 u
= 1 u
Number of pink stickers that Min gave away
= 4 u - 1 u
= 3 u
Fraction of the pink stickers that Min gave away =
34 Answer(s):
34
