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.

What are irrational numbers good for?

They don’t seek to make things harder for themselves, they seek to make them easier. Irrational numbers simplify. They fill in all the holes that exist in the set of rational numbers and make it possible to study limits, continuity, derivatives, integrals and so on. None of that is doable without irrational numbers.

What are 5 examples of rational numbers?

Some of the examples of rational number are 1/2, 1/5, 3/4, and so on. The number “0” is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc. But, 1/0, 2/0, 3/0, etc. are not rational, since they give us infinite values.
