| 1. What are real numbers and why are they important in mathematics? |  |
Ans. Real numbers are a set of numbers that include rational numbers (such as fractions and integers) as well as irrational numbers (such as square roots and pi). They are important in mathematics because they provide a complete and continuous number line, allowing for precise measurements and calculations in various mathematical concepts.
| 2. How can understanding real numbers help in everyday life? | |
Ans. Understanding real numbers can help in everyday life by enabling us to make sense of measurements, quantities, and comparisons. For example, knowing real numbers helps us understand distance, time, temperature, money, and many other aspects of our daily lives.
| 3. What are some common operations performed with real numbers? | |
Ans. Some common operations performed with real numbers include addition, subtraction, multiplication, and division. These operations allow for calculations, comparisons, and solving equations involving real numbers.
| 4. Are all real numbers rational? | |
Ans. No, not all real numbers are rational. Real numbers include both rational and irrational numbers. Rational numbers can be expressed as a fraction or a ratio of two integers, while irrational numbers cannot be expressed as a fraction and have an infinite number of non-repeating decimals.
| 5. How can one determine if a number is rational or irrational? | |
Ans. A number can be determined as rational or irrational based on its decimal representation. If a number has a terminating or repeating decimal, it is rational. If a number has a non-terminating and non-repeating decimal, it is irrational. Another method is to check if the number can be expressed as a fraction. If it can, then it is rational; otherwise, it is irrational.
