PSLE At first, Joelle had an equal number of yellow and orange stickers . She gave away
25 of her yellow stickers and some orange stickers. In the end, she was left with
23 of her stickers. What fraction of the orange stickers was Joelle left with?
|
Yellow |
Orange |
Total |
Comparing yellow stickers and orange stickers at first |
1x5x3 = 15 u |
1x5x3 = 15 u |
2x5x3 = 30 u |
Before |
5x3 = 15 u |
15 u |
3x10 = 30 u |
Change |
- 2x3 = - 6 u |
- 4 u |
- 2x10 = - 10 u |
After |
3x3 = 9 u |
11 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 orange stickers that Joelle was left with
= 20 u - 9 u
= 11 u
Fraction of the orange stickers that Joelle was left with =
