Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That’s because pi is what mathematicians call an “infinite decimal” — after the decimal point, the digits go on forever and ever.
What is classification of numbers?
The classifications of numbers are: real number, imaginary numbers, irrational number, integers, whole numbers, and natural numbers. Real numbers are numbers that land somewhere on a number line. Imaginary numbers are numbers that involve the number i, which represents √−1.
Is Pi irrational?
No matter how big your circle, the ratio of circumference to diameter is the value of Pi. Pi is an irrational number—you can’t write it down as a non-infinite decimal. This means you need an approximate value for Pi.
How do you classify a number rational or irrational?
A rational number is the one which can be represented in the form of P/Q where P and Q are integers and Q ≠ 0. But an irrational number cannot be written in the form of simple fractions. ⅔ is an example of a rational number whereas √2 is an irrational number.
