PSLE At first, Linda had an equal number of pink and yellow beads . She gave away
35 of her pink beads and some yellow beads. In the end, she was left with
23 of her beads. What fraction of the yellow beads was Linda left with?
|
Pink |
Yellow |
Total |
Comparing pink beads and yellow beads at first |
1x5x3 = 15 u |
1x5x3 = 15 u |
2x5x3 = 30 u |
Before |
5x3 = 15 u |
15 u |
3x10 = 30 u |
Change |
- 3x3 = - 9 u |
- 1 u |
- 2x10 = - 10 u |
After |
2x3 = 6 u |
14 u |
1x10 = 20 u |
The number of pink beads at first is repeated. Make the number of pink 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 3 is 30.
Number of yellow beads that Linda was left with
= 20 u - 6 u
= 14 u
Fraction of the yellow beads that Linda was left with =
