PSLE At first, Dana had an equal number of silver and pink stickers . She gave away
25 of her silver stickers and some pink stickers. In the end, she was left with
34 of her stickers. What fraction of the pink stickers was Dana left with?
|
Silver |
Pink |
Total |
Comparing silver stickers and pink stickers at first |
1x5x2 = 10 u |
1x5x2 = 10 u |
2x5x2 = 20 u |
Before |
5x2 = 10 u |
10 u |
4x5 = 20 u |
Change |
- 2x2 = - 4 u |
- 1 u |
- 3x5 = - 5 u |
After |
3x2 = 6 u |
9 u |
1x5 = 15 u |
The number of silver stickers at first is repeated. Make the number of silver 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 4 is 20.
Number of pink stickers that Dana was left with
= 15 u - 6 u
= 9 u
Fraction of the pink stickers that Dana was left with =
