PSLE At first, Anna had an equal number of green and gold stickers . She gave away
45 of her green stickers and some gold stickers. In the end, she was left with
25 of her stickers. What fraction of the gold stickers was Anna left with?
|
Green |
Gold |
Total |
Comparing green stickers and gold stickers at first |
1x5x1 = 5 u |
1x5x1 = 5 u |
2x5x1 = 10 u |
Before |
5x1 = 5 u |
5 u |
5x2 = 10 u |
Change |
- 4x1 = - 4 u |
- 2 u |
- 2x2 = - 6 u |
After |
1x1 = 1 u |
3 u |
3x2 = 4 u |
The number of green stickers at first is repeated. Make the number of green 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 gold stickers that Anna was left with
= 4 u - 1 u
= 3 u
Fraction of the gold stickers that Anna was left with =
35 Answer(s):
35
