## Is 0.3333 a rational number?

0.3333 is both recurring and non terminating – it’s a rational number .

## How do I tell if a number is rational?

To decide if an integer is a rational number, we try to write it as a ratio of two integers. An easy way to do this is to write it as a fraction with denominator one. Since any integer can be written as the ratio of two integers, all integers are rational numbers.

## Is 0 a rational number?

Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero.

## Is 7.478478478 a rational number?

Answer. so its an irrational number.

## How do you know if it is rational or irrational?

A rational number can be defined as any number that can be expressed or written in the p/q form, where ‘p’ and ‘q’ are integers and q is a non-zero number. An irrational number on the other hand cannot be expressed in p/q form and the decimal expansion of an irrational number is non-repeating and non-terminating.

## Is 1 3 a rational or irrational number?

A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.

## Is 2/3 a rational or irrational number?

In mathematics rational means “ratio like.” So a rational number is one that can be written as the ratio of two integers. For example 3=3/1, −17, and 2/3 are rational numbers.
