PSLE At first, Hilda had an equal number of blue and red marbles . She gave away
34 of her blue marbles and some red marbles. In the end, she was left with
14 of her marbles. What fraction of the red marbles was Hilda left with?
|
Blue |
Red |
Total |
Comparing blue marbles and red marbles at first |
1x4x1 = 4 u |
1x4x1 = 4 u |
2x4x1 = 8 u |
Before |
4x1 = 4 u |
4 u |
4x2 = 8 u |
Change |
- 3x1 = - 3 u |
- 3 u |
- 1x2 = - 6 u |
After |
1x1 = 1 u |
1 u |
3x2 = 2 u |
The number of blue marbles at first is repeated. Make the number of blue marbles the first the same. LCM of 4 and 1 is 4.
The total number of marbles at first is repeated. Make the total number of marbles at first the same. LCM of 8 and 4 is 8.
Number of red marbles that Hilda was left with
= 2 u - 1 u
= 1 u
Fraction of the red marbles that Hilda was left with =
14 Answer(s):
14
