In a box, 41% of the beads are green, 14% are white and the rest are black
- What fraction of the beads is black? Give your answer in the simplest form.
- There are 675 black beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are black
= 100% - 41% - 14%
= 45%
Fraction of beads that are black
=
45100 =
920 (b)
Number of black beads = 9 u
9 u = 675
1 u = 675 ÷ 9 = 75
Total number of beads
= 20 u
= 20 x 75
= 1500
Answer(s): (a)
920; (b) 1500
