PSLE At first, Tammy had an equal number of orange and blue stickers . She gave away
25 of her orange stickers and some blue stickers. In the end, she was left with
23 of her stickers. What fraction of the blue stickers was Tammy left with?
|
Orange |
Blue |
Total |
Comparing orange stickers and blue stickers at first |
1x5x3 = 15 u |
1x5x3 = 15 u |
2x5x3 = 30 u |
Before |
5x3 = 15 u |
15 u |
3x10 = 30 u |
Change |
- 2x3 = - 6 u |
- 4 u |
- 2x10 = - 10 u |
After |
3x3 = 9 u |
11 u |
1x10 = 20 u |
The number of orange stickers at first is repeated. Make the number of orange 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 blue stickers that Tammy was left with
= 20 u - 9 u
= 11 u
Fraction of the blue stickers that Tammy was left with =
