PSLE At first, Vanessa had an equal number of silver and red stickers . She gave away
35 of her silver stickers and some red stickers. In the end, she was left with
23 of her stickers. What fraction of the red stickers was Vanessa left with?
|
Silver |
Red |
Total |
Comparing silver stickers and red stickers at first |
1x5x3 = 15 u |
1x5x3 = 15 u |
2x5x3 = 30 u |
Before |
5x3 = 15 u |
15 u |
3x10 = 30 u |
Change |
- 3x3 = - 9 u |
- 1 u |
- 2x10 = - 10 u |
After |
2x3 = 6 u |
14 u |
1x10 = 20 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 3 is 30.
Number of red stickers that Vanessa was left with
= 20 u - 6 u
= 14 u
Fraction of the red stickers that Vanessa was left with =
