PSLE At first, Jane had an equal number of purple and red beads . She gave away
34 of her purple beads and some red beads. In the end, she was left with
14 of her beads. What fraction of the red beads was Jane left with?
|
Purple |
Red |
Total |
Comparing purple beads and red beads 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 purple beads at first is repeated. Make the number of purple beads the first the same. LCM of 4 and 1 is 4.
The total number of beads at first is repeated. Make the total number of beads at first the same. LCM of 8 and 4 is 8.
Number of red beads that Jane was left with
= 2 u - 1 u
= 1 u
Fraction of the red beads that Jane was left with =
14 Answer(s):
14
