PSLE At first, Emily had an equal number of silver and blue marbles . She gave away
23 of her silver marbles and some blue marbles. In the end, she was left with
35 of her marbles. What fraction of the blue marbles was Emily left with?
|
Silver |
Blue |
Total |
Comparing silver marbles and blue marbles 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 silver marbles at first is repeated. Make the number of silver marbles the first the same. LCM of 3 and 1 is 3.
The total number of marbles at first is repeated. Make the total number of marbles at first the same. LCM of 6 and 5 is 30.
Number of blue marbles that Emily was left with
= 18 u - 5 u
= 13 u
Fraction of the blue marbles that Emily was left with =
