Question

Express the following integer as a rational number with denominator $7$. (iii)$0$.

Answer 1

We know that,
If $p$ and $q$ is an integer and $q\ne 0$, then the number of the form $\frac{p}{q}$ is called a rational number.

Given , number is $0$.

And $0$ can be written as:
$0=\frac{0}{1}$

$\Rightarrow$ $\frac{0}{1}=\frac{0\times 7}{1\times 7}$

[Using the concept of an equivalent rational number]

$=\frac{0}{7}$

Hence, the required rational number is $\frac{0}{7}$.
