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