PSLE At first, Jade had an equal number of gold and blue marbles . She gave away
35 of her gold marbles and some blue marbles. In the end, she was left with
23 of her marbles. What fraction of the blue marbles was Jade left with?
|
Gold |
Blue |
Total |
Comparing gold marbles and blue marbles 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 gold marbles at first is repeated. Make the number of gold marbles the first the same. LCM of 5 and 1 is 5.
The total number of marbles at first is repeated. Make the total number of marbles at first the same. LCM of 10 and 3 is 30.
Number of blue marbles that Jade was left with
= 20 u - 6 u
= 14 u
Fraction of the blue marbles that Jade was left with =
