PSLE At first, Shannon had an equal number of purple and orange beads . She gave away
23 of her purple beads and some orange beads. In the end, she was left with
25 of her beads. What fraction of the orange beads was Shannon left with?
|
Purple |
Orange |
Total |
Comparing purple beads and orange beads at first |
1x3x5 = 15 u |
1x3x5 = 15 u |
2x3x5 = 30 u |
Before |
3x5 = 15 u |
15 u |
5x6 = 30 u |
Change |
- 2x5 = - 10 u |
- 8 u |
- 2x6 = - 18 u |
After |
1x5 = 5 u |
7 u |
3x6 = 12 u |
The number of purple beads at first is repeated. Make the number of purple beads the first the same. LCM of 3 and 1 is 3.
The total number of beads at first is repeated. Make the total number of beads at first the same. LCM of 6 and 5 is 30.
Number of orange beads that Shannon was left with
= 12 u - 5 u
= 7 u
Fraction of the orange beads that Shannon was left with =
715 Answer(s):
715
