PSLE At first, Opal had an equal number of gold and orange stickers . She gave away
34 of her gold stickers and some orange stickers. In the end, she was left with
14 of her stickers. What fraction of the orange stickers did Opal give away?
|
Gold |
Orange |
Total |
Comparing gold stickers and orange stickers at first |
1x4x1 = 4 u |
1x4x1 = 4 u |
2x4x1 = 8 u |
Before |
4x1 = 4 u |
4 u |
4x2 = 8 u |
Change |
- 3x1 = - 3 u |
- 3 u |
- 1x2 = - 6 u |
After |
1x1 = 1 u |
1 u |
3x2 = 2 u |
After
1x1 =
1 u1 u
3x2 =
2 uThe number of gold stickers at first is repeated. Make the number of gold stickers the first the same. LCM of 4 and 1 is 4.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 8 and 4 is 8.
Number of orange stickers that Opal was left with
= 2 u - 1 u
= 1 u
Number of orange stickers that Opal gave away
= 4 u - 1 u
= 3 u
Fraction of the orange stickers that Opal gave away =
34 Answer(s):
34
