Question

there are 400 beads of the same size. 35% are red. 2/5 of the remaining are blue. the rest are white. what fraction are there white beads?

Answer 1

84/400

Explanation:

First, divide 35 by 100 to get the decimal, 0.35. Then, multiply 0.35 x 400. You should get 140. Now the question says 2/5 of the remaining are blue. You need to multiply 2/5 x 140 to get 56. 56 are blue. So now subtract 56 from 140 to get 84. The answer (not in simplest form) is 84/400.
