PSLE At first, Mary had an equal number of green and pink stickers . She gave away
23 of her green stickers and some pink stickers. In the end, she was left with
35 of her stickers. What fraction of the pink stickers was Mary left with?
|
Green |
Pink |
Total |
Comparing green 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 |
- 2 u |
- 3x6 = - 12 u |
After |
1x5 = 5 u |
13 u |
2x6 = 18 u |
The number of green stickers at first is repeated. Make the number of green 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 Mary was left with
= 18 u - 5 u
= 13 u
Fraction of the pink stickers that Mary was left with =
