In a box, 50% of the erasers are purple, 20% are silver and the rest are green
- What fraction of the erasers is green? Give your answer in the simplest form.
- There are 498 green erasers in the box. How many erasers are there in the box altogether?
(a)
Percentage of erasers that are green
= 100% - 50% - 20%
= 30%
Fraction of erasers that are green
=
30100 =
310 (b)
Number of green erasers = 3 u
3 u = 498
1 u = 498 ÷ 3 = 166
Total number of erasers
= 10 u
= 10 x 166
= 1660
Answer(s): (a)
310; (b) 1660
