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

Orange |
Silver |
Total |
Comparing orange stickers and silver 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 orange stickers at first is repeated. Make the number of orange 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 silver stickers that Usha was left with
= 3 u - 2 u
= 1 u
Number of silver stickers that Usha gave away
= 6 u - 1 u
= 5 u
Fraction of the silver stickers that Usha gave away =
