PSLE At first, Dana had an equal number of orange and gold stickers . She gave away
35 of her orange stickers and some gold stickers. In the end, she was left with
23 of her stickers. What fraction of the gold stickers was Dana left with?
|
Orange |
Gold |
Total |
Comparing orange stickers and gold stickers at first |
1x5x3 = 15 u |
1x5x3 = 15 u |
2x5x3 = 30 u |
Before |
5x3 = 15 u |
15 u |
3x10 = 30 u |
Change |
- 3x3 = - 9 u |
- 1 u |
- 2x10 = - 10 u |
After |
2x3 = 6 u |
14 u |
1x10 = 20 u |
The 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 3 is 30.
Number of gold stickers that Dana was left with
= 20 u - 6 u
= 14 u
Fraction of the gold stickers that Dana was left with =
