Question

In a book shop, $\frac{5}{12}$ of the people are males. Write the ratio of males and females in the shop.

Answer 1

Males are $\frac{5}{12}$

Then females becomes $1-\frac{5}{12}=\frac{12-5}{12}=\frac{7}{12}$

So, the ratio can be expressed as $\frac{5}{12}:\frac{7}{12}$

Taking the LCM of $12and12$ i.e. $12$

Multiply both terms by $12$, we get $\frac{5}{12}\times 12:\frac{7}{12}\times 12$

$5:7$

Hence, ratio of males to females are $5:7$
