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

Comparing red stickers and orange stickers at first |
1x3x2 = 6 u |
1x3x2 = 6 u |
2x3x2 = 12 u |
Before |
3x2 = 6 u |
6 u |
4x3 = 12 u |
Change |
- 2x2 = - 4 u |
- 5 u |
- 1x3 = - 9 u |
After |
1x2 = 2 u |
1 u |
3x3 = 3 u |
After
1x2 =
2 u1 u
3x3 =
3 uThe number of red stickers at first is repeated. Make the number of red 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 4 is 12.
Number of orange stickers that Jane was left with
= 3 u - 2 u
= 1 u
Number of orange stickers that Jane gave away
= 6 u - 1 u
= 5 u
Fraction of the orange stickers that Jane gave away =
