# Can pi be expressed as a fraction?

The number pi represented as 'π' is a mathematical constant.

## Answer: Pi cannot be expressed as a fraction as it is an irrational number.

Let's understand the steps

**Explanation:**

In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find the area of a circle by multiplying the radius squared times pi.

However, pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction also known as a non-terminating non-recurring decimal.

That's because pi is what mathematicians call an "infinite decimal" - after the decimal point, the digits go on forever and ever without repetition.

Although pi is commonly estimated by the fraction 22/7, it cannot officially be expressed in a simple fraction accurately, owing to its irrationality.

The approximate value of pi is 3.14...
