In a box, 46% of the beads are red, 12% are grey and the rest are blue
- What fraction of the beads is blue? Give your answer in the simplest form.
- There are 504 blue beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are blue
= 100% - 46% - 12%
= 42%
Fraction of beads that are blue
=
42100 =
2150 (b)
Number of blue beads = 21 u
21 u = 504
1 u = 504 ÷ 21 = 24
Total number of beads
= 50 u
= 50 x 24
= 1200
Answer(s): (a)
2150; (b) 1200
