How are real numbers used in everyday life?
Most numbers that we work with every day are real numbers. These include all of the money that’s in your wallet, the statistics you see in sports, or the measurements we see in cookbooks. All of these numbers can be represented as a fraction (whether we like it or not).
Why are real numbers very important in our world?
Real numbers are all the numbers on the number line, and there are infinitely many of them. Their types and categories are important because they can give you more information about the problem you are looking at. In fact, certain types of numbers can direct you to further formulas or definitions in mathematics.
What are 5 examples of real numbers?

What is real number explain with example?
Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
What are the properties of real numbers and examples?
| Property (a, b and c are real numbers, variables or algebraic expressions) | Examples | |
|---|---|---|
| 8. | Additive Inverse Property a + (-a) = 0 | 4 + (-4) = 0 |
| 9. | Multiplicative Inverse Property | |
| 10. | Zero Property of Multiplication a • 0 = 0 | 4 • 0 = 0 |
| 11. | Closure Property of Addition a + b is a real number | 10 + 5 = 15 (a real number) |
