Question

Classify the following numbers as rational or irrational :

$\left(i\right)\frac{22}{7}$

Answer 1

Solution:

Classify that the number is rational or irrational:

A rational number can be written in $\frac{p}{q}$ form, where $pandq$are integers and $q\ne 0$.

Let, $\frac{p}{q}=\frac{22}{7}$, where, $p=22andq=7$and both numbers $22and7$are integers and $7\ne 0$.

Here, we can express the given number in $\frac{p}{q}$form which satisfies the condition of rational numbers.

Final answer: Hence, the number $\frac{22}{7}$ is a rational number.
