In a box, 40% of the erasers are yellow, 15% are pink and the rest are red
- What fraction of the erasers is red? Give your answer in the simplest form.
- There are 477 red erasers in the box. How many erasers are there in the box altogether?
(a)
Percentage of erasers that are red
= 100% - 40% - 15%
= 45%
Fraction of erasers that are red
=
45100 =
920 (b)
Number of red erasers = 9 u
9 u = 477
1 u = 477 ÷ 9 = 53
Total number of erasers
= 20 u
= 20 x 53
= 1060
Answer(s): (a)
920; (b) 1060
