In a box, 46% of the stamps are grey, 12% are red and the rest are white
- What fraction of the stamps is white? Give your answer in the simplest form.
- There are 441 white stamps in the box. How many stamps are there in the box altogether?
(a)
Percentage of stamps that are white
= 100% - 46% - 12%
= 42%
Fraction of stamps that are white
=
42100 =
2150 (b)
Number of white stamps = 21 u
21 u = 441
1 u = 441 ÷ 21 = 21
Total number of stamps
= 50 u
= 50 x 21
= 1050
Answer(s): (a)
2150; (b) 1050
