PSLE At first, Kimberly had an equal number of orange and silver marbles . She gave away
35 of her orange marbles and some silver marbles. In the end, she was left with
23 of her marbles. What fraction of the silver marbles was Kimberly left with?
|
Orange |
Silver |
Total |
Comparing orange marbles and silver 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 orange marbles at first is repeated. Make the number of orange 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 silver marbles that Kimberly was left with
= 20 u - 6 u
= 14 u
Fraction of the silver marbles that Kimberly was left with =
