PSLE At first, Linda had an equal number of black and green stickers . She gave away
23 of her black stickers and some green stickers. In the end, she was left with
25 of her stickers. What fraction of the green stickers was Linda left with?
|
Black |
Green |
Total |
Comparing black stickers and green 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 black stickers at first is repeated. Make the number of black 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 green stickers that Linda was left with
= 12 u - 5 u
= 7 u
Fraction of the green stickers that Linda was left with =
