Question

Express the following integer as a rational number with denominator $7$.​
(v) $7$.

​

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 $7$.

And $7$ can be written as:

$7=\frac{7}{1}$

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

[Using the concept of an equivalent rational number]

$=\frac{49}{7}$

Hence, the required rational number is $\frac{49}{7}$.
