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

Orange |
Blue |
Total |
Comparing orange stickers and blue stickers at first |
1x5x2 = 10 u |
1x5x2 = 10 u |
2x5x2 = 20 u |
Before |
5x2 = 10 u |
10 u |
4x5 = 20 u |
Change |
- 3x2 = - 6 u |
- 9 u |
- 1x5 = - 15 u |
After |
2x2 = 4 u |
1 u |
3x5 = 5 u |
After
2x2 =
4 u1 u
3x5 =
5 uThe number of orange stickers at first is repeated. Make the number of orange 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 4 is 20.
Number of blue stickers that Gem was left with
= 5 u - 4 u
= 1 u
Number of blue stickers that Gem gave away
= 10 u - 1 u
= 9 u
Fraction of the blue stickers that Gem gave away =
