PSLE At first, Roshel had an equal number of silver and green stickers . She gave away
25 of her silver stickers and some green stickers. In the end, she was left with
35 of her stickers. What fraction of the green stickers did Roshel give away?

Silver |
Green |
Total |
Comparing silver stickers and green stickers at first |
1x5x1 = 5 u |
1x5x1 = 5 u |
2x5x1 = 10 u |
Before |
5x1 = 5 u |
5 u |
5x2 = 10 u |
Change |
- 2x1 = - 2 u |
- 2 u |
- 3x2 = - 4 u |
After |
3x1 = 3 u |
3 u |
2x2 = 6 u |
After
3x1 =
3 u3 u
2x2 =
6 uThe number of silver stickers at first is repeated. Make the number of silver stickers the first the same. LCM of 5 and 1 is 5.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 10 and 5 is 10.
Number of green stickers that Roshel was left with
= 6 u - 3 u
= 3 u
Number of green stickers that Roshel gave away
= 5 u - 3 u
= 2 u
Fraction of the green stickers that Roshel gave away =
25 Answer(s):
25
