PSLE At first, Fanny had an equal number of pink and purple stickers . She gave away
23 of her pink stickers and some purple stickers. In the end, she was left with
25 of her stickers. What fraction of the purple stickers was Fanny left with?
|
Pink |
Purple |
Total |
Comparing pink stickers and purple stickers at first |
1x3x5 = 15 u |
1x3x5 = 15 u |
2x3x5 = 30 u |
Before |
3x5 = 15 u |
15 u |
5x6 = 30 u |
Change |
- 2x5 = - 10 u |
- 8 u |
- 2x6 = - 18 u |
After |
1x5 = 5 u |
7 u |
3x6 = 12 u |
The number of pink stickers at first is repeated. Make the number of pink stickers the first the same. LCM of 3 and 1 is 3.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 6 and 5 is 30.
Number of purple stickers that Fanny was left with
= 12 u - 5 u
= 7 u
Fraction of the purple stickers that Fanny was left with =
