Question

The product of two fractions is $20$. If one of the fractions is $\frac{1}{4}$, then the other fraction is ___.

Answer 1

Let the other fraction be $x$

It is given that the product of two fractions is $20$, where one fraction is $\frac{1}{4}$.
Then, $x\times \frac{1}{4}=20$
$\Rightarrow x=20\times 4$
$\therefore x=80$

Hence, the other fraction is $\frac{80}{1}$.
