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