PSLE At first, Fiona had an equal number of silver and gold beads . She gave away
25 of her silver beads and some gold beads. In the end, she was left with
35 of her beads. What fraction of the gold beads was Fiona left with?
|
Silver |
Gold |
Total |
Comparing silver beads and gold beads at first |
1x5x1 = 5 u |
1x5x1 = 5 u |
2x5x1 = 10 u |
Before |
5x1 = 5 u |
5 u |
5x2 = 10 u |
Change |
- 2x1 = - 2 u |
- 2 u |
- 3x2 = - 4 u |
After |
3x1 = 3 u |
3 u |
2x2 = 6 u |
The number of silver beads at first is repeated. Make the number of silver beads the first the same. LCM of 5 and 1 is 5.
The total number of beads at first is repeated. Make the total number of beads at first the same. LCM of 10 and 5 is 10.
Number of gold beads that Fiona was left with
= 6 u - 3 u
= 3 u
Fraction of the gold beads that Fiona was left with =
35 Answer(s):
35
