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

Blue |
Orange |
Total |
Comparing blue stickers and orange stickers at first |
1x3x5 = 15 u |
1x3x5 = 15 u |
2x3x5 = 30 u |
Before |
3x5 = 15 u |
15 u |
5x6 = 30 u |
Change |
- 2x5 = - 10 u |
- 2 u |
- 3x6 = - 12 u |
After |
1x5 = 5 u |
13 u |
2x6 = 18 u |
After
1x5 =
5 u13 u
2x6 =
18 uThe number of blue stickers at first is repeated. Make the number of blue stickers the first the same. LCM of 3 and 1 is 3.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 6 and 5 is 30.
Number of orange stickers that Gem was left with
= 18 u - 5 u
= 13 u
Number of orange stickers that Gem gave away
= 15 u - 13 u
= 2 u
Fraction of the orange stickers that Gem gave away =
