Question

Re are 8 times as many males as females on the maths course at university. What fraction of the course are female?

Give your answer in its simplest form.

Answer 1

8/9

Explanation:

Let

x = number of miles on the math course

There are 8 times as many males as females

Number of females = 8x

Total students of the course = number of males + number of females

= x + 8x

= 9x

Total students of the course = 9x

What fraction of the course are female?

Fraction of the course that are females = number of females / Total students of the course

= 8x / 9x

= 8/9

Fraction of the course that are females = 8/9
