PSLE At first, Jane had an equal number of black and purple stickers . She gave away
34 of her black stickers and some purple stickers. In the end, she was left with
25 of her stickers. What fraction of the purple stickers was Jane left with?
|
Black |
Purple |
Total |
Comparing black stickers and purple stickers at first |
1x4x5 = 20 u |
1x4x5 = 20 u |
2x4x5 = 40 u |
Before |
4x5 = 20 u |
20 u |
5x8 = 40 u |
Change |
- 3x5 = - 15 u |
- 9 u |
- 2x8 = - 24 u |
After |
1x5 = 5 u |
11 u |
3x8 = 16 u |
The number of black stickers at first is repeated. Make the number of black stickers the first the same. LCM of 4 and 1 is 4.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 8 and 5 is 40.
Number of purple stickers that Jane was left with
= 16 u - 5 u
= 11 u
Fraction of the purple stickers that Jane was left with =
