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