Question

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

• A. 80/1
• B. $\frac{40}{1}$
• C. $\frac{80}{20}$
• D. $\frac{80}{4}$

Answer 1

The correct option is A

80/1

Let the other fraction be $x$

Then, according to question $x\times \frac{1}{4}=20$

$x=20\times 4=80$
$x=80$

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