PSLE At first, Wendy had an equal number of green and orange stickers . She gave away
25 of her green stickers and some orange stickers. In the end, she was left with
23 of her stickers. What fraction of the orange stickers was Wendy left with?
|
Green |
Orange |
Total |
Comparing green 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 green stickers at first is repeated. Make the number of green 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 Wendy was left with
= 20 u - 9 u
= 11 u
Fraction of the orange stickers that Wendy was left with =
