In a box, 44% of the beads are red, 20% are grey and the rest are white
- What fraction of the beads is white? Give your answer in the simplest form.
- There are 666 white beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are white
= 100% - 44% - 20%
= 36%
Fraction of beads that are white
=
36100 =
925 (b)
Number of white beads = 9 u
9 u = 666
1 u = 666 ÷ 9 = 74
Total number of beads
= 25 u
= 25 x 74
= 1850
Answer(s): (a)
925; (b) 1850
