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