Question

What will be the value obtained when 20 is divided by $\frac{1}{20}$?

Answer 1

For the division of a whole number by a fraction, we need to multiply the reciprocal of the fraction by the whole number.
The reciprocal of $\frac{1}{20}$ is 20. This implies, $20\times 20=400.$ Therefore, $20÷\frac{1}{20}=400.$
