PSLE At first, Betty had an equal number of yellow and gold stickers . She gave away
35 of her yellow stickers and some gold stickers. In the end, she was left with
23 of her stickers. What fraction of the gold stickers was Betty left with?
|
Yellow |
Gold |
Total |
Comparing yellow 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 yellow stickers at first is repeated. Make the number of yellow 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 Betty was left with
= 20 u - 6 u
= 14 u
Fraction of the gold stickers that Betty was left with =
