PSLE At first, Kimberly had an equal number of pink and black beads . She gave away
34 of her pink beads and some black beads. In the end, she was left with
35 of her beads. What fraction of the black beads was Kimberly left with?
|
Pink |
Black |
Total |
Comparing pink beads and black beads at first |
1x4x5 = 20 u |
1x4x5 = 20 u |
2x4x5 = 40 u |
Before |
4x5 = 20 u |
20 u |
5x8 = 40 u |
Change |
- 3x5 = - 15 u |
- 1 u |
- 3x8 = - 16 u |
After |
1x5 = 5 u |
19 u |
2x8 = 24 u |
The number of pink beads at first is repeated. Make the number of pink 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 5 is 40.
Number of black beads that Kimberly was left with
= 24 u - 5 u
= 19 u
Fraction of the black beads that Kimberly was left with =
