## Are square roots of decimals always irrational?

If you see a long decimal number, that square root IS irrational. The proof that √2 is indeed irrational does not rely on computers at all but instead is a proof by contradiction: if √2 WAS a rational number, then we’d get a contradiction.

**How do you determine if a decimal is rational or irrational?**

Answer: If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.

**Can square roots of decimal numbers be rational numbers?**

If you are asking that can square root of decimal numbers be rational ,Yes they can be rational but not not always For example square root of 0.25 is 0.5 which is a rational number.

### What is the difference between rational and irrational decimal?

For example, one third in decimal form is 0.33333333333333 (the threes go on forever). Just so, how do you tell if a decimal is rational or irrational? All numbers that are not rational are considered irrational.

**What are rational numbers in math?**

Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. So, any terminating decimal is a rational number. Additionally, is rational or irrational? A rational number is a number that can be express as the ratio of two integers.

**Is √7 a rational number?**

A rational number is a sort of real number that has the form p/q where q≠0. When a rational number is split, the result is a decimal number, which can be either a terminating or a recurring decimal. Here, the given number, √7 cannot be expressed in the form of p/q. Alternatively, 7 is a prime number.
