In a box, 30% of the beads are silver, 10% are gold and the rest are white
- What fraction of the beads is white? Give your answer in the simplest form.
- There are 450 white beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are white
= 100% - 30% - 10%
= 60%
Fraction of beads that are white
=
60100 =
35 (b)
Number of white beads = 3 u
3 u = 450
1 u = 450 ÷ 3 = 150
Total number of beads
= 5 u
= 5 x 150
= 750
Answer(s): (a)
35; (b) 750
