# Question: Is 0.3333 A Rational Number?

## How do you know if a number is irrational?

An irrational number is a number that cannot be written as the ratio of two integers.

Its decimal form does not stop and does not repeat..

## Is 0.004 a rational number?

Solution : Rational numbers are the number which can be written in the form of p/q where p and q are integers and q is non-zero. … As cannot be written in the form of p/q so it is irrational number. Therefore, is an irrational number.

## Is 3.125 a rational number?

Other examples of rational numbers are decimals with finite decimal numbers (e.g. 3.125=\frac{25}{8}) and decimals with a repeating pattern (e.g. 1.33333333333…). … There is no finite end to \pi, so it is considered an irrational number.

## Why is 0.3333 a rational number?

Definition of Rationality: A number that can be represented in the form pq where p and q are integers (q not equal to zero) is a rational number. 0.3333… =13; hence it is a rational number.

## Is 22 7 A rational or irrational number?

22/7 is a rational number. All rational numbers can be expressed as a fraction whose denominator is non zero. Whereas, pi cannot be expressed in the fraction of two integers and has no accurate decimal value, so pi is an irrational number.

## Is 2 0 an irrational number?

Irrationals aren’t merely “not rational”, they’re real numbers that aren’t rational. Since 10 doesn’t evaluate to a real number (or any kind of number at all, if you’re working in R), it’s neither rational nor irrational. It’s non-existent.

## How do you know if its rational or irrational?

To show that the rational numbers are dense: An irrational number is a number that is NOT rational. It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.

## Is 0.3333 a terminating decimal?

For example, 0.3333… and 9.257257… are repeating decimals. To indicate that a decimal is repeating, a bar is drawn above the digit or group of digits that repeats. For example, 0.3333… can be written as 0.3 with a bar over the 3. … Since 5 divided into 4 is 0.8, 4/5 can be written as a terminating decimal.

## Is 1.33 rational or irrational?

Yes, it is a rational number.

## Is 0.75 a terminating decimal?

Solution. Step 2: We find that on long division 34=0.75 which is a terminating decimal.

## Is 0.25 a terminating decimal?

A terminating decimal, true to its name, is a decimal that has an end. For example, 1 / 4 can be expressed as a terminating decimal: It is 0.25.

## Is 5 a rational number?

## Which is the smallest irrational number?

root2The smallest irrational number is – root2 since 3+ root2 +(-root2)= 3+root2-root2=3( a rational number).

## What is the smallest rational number?

01 Answer. 0 is the smallest rational number.

## How do you tell if a number 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 3.33333 a rational number?

1 Answer. 3.33333………… =103 It is rational because it can be written in the form pq , therefore it is not irrational.

## 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. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer.
