PSLE At first, Tiffany had an equal number of yellow and purple beads . She gave away
34 of her yellow beads and some purple beads. In the end, she was left with
35 of her beads. What fraction of the purple beads was Tiffany left with?
|
Yellow |
Purple |
Total |
Comparing yellow beads and purple 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 yellow beads at first is repeated. Make the number of yellow 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 purple beads that Tiffany was left with
= 24 u - 5 u
= 19 u
Fraction of the purple beads that Tiffany was left with =
