Whole numbers can always be expressed as the ratio of two real numbers (a simple fraction). An irrational number is a real number that can not be written as a simple fraction (terminating decimal or repeating decimal). Therefore whole numbers can not be irrational.

Are fractions irrational numbers?

The definition of rational numbers tells us that all fractions are rational. We will now look at the counting numbers, whole numbers, integers, and decimals to make sure they are rational. Since any integer can be written as the ratio of two integers, all integers are rational numbers.

Are irrational numbers always real numbers?

An irrational number is a real number that cannot be reduced to any ratio between an integer p and a natural number q . The union of the set of irrational numbers and the set of rational numbers forms the set of real numbers.

Are all natural numbers real numbers?

Real numbers are mainly classified into rational and irrational numbers. Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.

Is 13 an irrational number?

The number 13 is an irrational number if 13 canNOT be expressed as a ratio, as in irRATIOnal. A quotient is the result you get when you divide one number by another number. For 13 to be an irrational number, the quotient of two integers canNOT equal 13.
