PSLE At first, Kimberly had an equal number of yellow and orange marbles . She gave away
25 of her yellow marbles and some orange marbles. In the end, she was left with
34 of her marbles. What fraction of the orange marbles did Kimberly give away?

Comparing yellow marbles and orange marbles at first |
1x5x2 = 10 u |
1x5x2 = 10 u |
2x5x2 = 20 u |
Before |
5x2 = 10 u |
10 u |
4x5 = 20 u |
Change |
- 2x2 = - 4 u |
- 1 u |
- 3x5 = - 5 u |
After |
3x2 = 6 u |
9 u |
1x5 = 15 u |
After
3x2 =
6 u9 u
1x5 =
15 uThe number of yellow marbles at first is repeated. Make the number of yellow 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 4 is 20.
Number of orange marbles that Kimberly was left with
= 15 u - 6 u
= 9 u
Number of orange marbles that Kimberly gave away
= 10 u - 9 u
= 1 u
Fraction of the orange marbles that Kimberly gave away =
