Answer 1

Interconversion of fractions and decimals

To convert the given fraction to a decimal we first change the denominator into a multiple of $10$.

Now, $40$ can be written in the multiples of $10$ as $40\times 25=1000$.

So, we multiply the numerator and denominator with $25$.

$\frac{3}{40}=\frac{3\times 25}{40\times 25}=\frac{75}{1000}=0.075$

Hence, $\frac{3}{40}=0.075$
