Question

A bag contains blue and yellow counters.

84% of the counters are blue.
Write the ratio of blue counters to yellow counters.
Give your answer in the form n: 1

Answer 1

5.25 : 1

Explanation:

If 84% of the counters are blue, then 16% of the counters are yellow.

percentage of yellow counters = 100% - 84% = 16%

blue counters : yellow counters = 84 : 16 (we don't write %)

Now divide with 16, so the second number becomes 1.

`(84)/(16) : (16)/(16) = 5.25 : 1`
