## Is negative 3 a rational number?

−3 is negative so it is not a natural or whole number. … Rational numbers are numbers that can be expressed as a fraction or ratio of two integers. Rational numbers are denoted Q . Since −3 can be written as −31 , it could be argued that −3 is also a real number.

## Why is 3.14 irrational?

Pi, which begins with 3.14, is one of the most common irrational numbers. … Pi has been calculated to over a quadrillion decimal places, but no pattern has ever been found; therefore it is an irrational number.

## Is Pi irrational?
