PSLE At first, Wendy had an equal number of pink and silver stickers . She gave away
23 of her pink stickers and some silver stickers. In the end, she was left with
35 of her stickers. What fraction of the silver stickers was Wendy left with?
|
Pink |
Silver |
Total |
Comparing pink stickers and silver 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 pink stickers at first is repeated. Make the number of pink 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 silver stickers that Wendy was left with
= 18 u - 5 u
= 13 u
Fraction of the silver stickers that Wendy was left with =
