In a box, 50% of the beads are gold, 20% are silver and the rest are brown
- What fraction of the beads is brown? Give your answer in the simplest form.
- There are 612 brown beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are brown
= 100% - 50% - 20%
= 30%
Fraction of beads that are brown
=
30100 =
310 (b)
Number of brown beads = 3 u
3 u = 612
1 u = 612 ÷ 3 = 204
Total number of beads
= 10 u
= 10 x 204
= 2040
Answer(s): (a)
310; (b) 2040
