Question

$\pi$ is an ________ while $\frac{22}{7}$ is rational.

• A. Integer
• B. Whole Number
  
• C. Rational Number
  
• D. Irrational Number
  

Answer 1

The correct option is D

Irrational Number

The value $\frac{22}{7}$ is a rational number, as it can be expressed in the form $\frac{p}{q}$.

We consider it as an approximate value of $\pi$ because $\pi$ is close to $\frac{22}{7}$.

But actually its value is $\mathrm{3.14159....}$, which is neither terminating nor repeating.

Thus, $\pi$ is irrational, but $\frac{22}{7}$ is rational.
