PSLE At first, Dana had an equal number of yellow and green beads . She gave away
23 of her yellow beads and some green beads. In the end, she was left with
35 of her beads. What fraction of the green beads was Dana left with?
|
Yellow |
Green |
Total |
Comparing yellow beads and green 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 |
- 2 u |
- 3x6 = - 12 u |
After |
1x5 = 5 u |
13 u |
2x6 = 18 u |
The number of yellow beads at first is repeated. Make the number of yellow 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 green beads that Dana was left with
= 18 u - 5 u
= 13 u
Fraction of the green beads that Dana was left with =
