In a box, 50% of the beads are red, 15% are grey and the rest are green
- What fraction of the beads is green? Give your answer in the simplest form.
- There are 532 green beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are green
= 100% - 50% - 15%
= 35%
Fraction of beads that are green
=
35100 =
720 (b)
Number of green beads = 7 u
7 u = 532
1 u = 532 ÷ 7 = 76
Total number of beads
= 20 u
= 20 x 76
= 1520
Answer(s): (a)
720; (b) 1520
