PSLE At first, Nicole had an equal number of purple and gold marbles . She gave away
23 of her purple marbles and some gold marbles. In the end, she was left with
35 of her marbles. What fraction of the gold marbles was Nicole left with?
|
Purple |
Gold |
Total |
Comparing purple marbles and gold 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 purple marbles at first is repeated. Make the number of purple 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 gold marbles that Nicole was left with
= 18 u - 5 u
= 13 u
Fraction of the gold marbles that Nicole was left with =
