PSLE At first, Yen had an equal number of pink and orange marbles . She gave away
23 of her pink marbles and some orange marbles. In the end, she was left with
14 of her marbles. What fraction of the orange marbles was Yen left with?
|
Pink |
Orange |
Total |
Comparing pink marbles and orange marbles at first |
1x3x2 = 6 u |
1x3x2 = 6 u |
2x3x2 = 12 u |
Before |
3x2 = 6 u |
6 u |
4x3 = 12 u |
Change |
- 2x2 = - 4 u |
- 5 u |
- 1x3 = - 9 u |
After |
1x2 = 2 u |
1 u |
3x3 = 3 u |
The number of pink marbles at first is repeated. Make the number of pink 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 4 is 12.
Number of orange marbles that Yen was left with
= 3 u - 2 u
= 1 u
Fraction of the orange marbles that Yen was left with =
