| 1. What are rational numbers? |  |
Ans. Rational numbers are numbers that can be expressed as a ratio of two integers, where the denominator is not zero. They can be written in the form a/b, where a and b are integers and b is not equal to zero.
| 2. How can rational numbers be represented on a number line? | |
Ans. Rational numbers can be represented on a number line by plotting a point at the corresponding location. Each rational number corresponds to a unique point on the number line, allowing for easy visualization and comparison.
| 3. Can all integers be considered rational numbers? | |
Ans. Yes, all integers can be considered rational numbers. Integers can be written in the form a/1, where a is an integer. Since integers can be expressed as a ratio of two integers, they are considered rational numbers.
| 4. Are rational numbers closed under addition and multiplication? | |
Ans. Yes, rational numbers are closed under addition and multiplication. When two rational numbers are added or multiplied, the result is also a rational number. This property makes rational numbers convenient for mathematical operations.
| 5. How can rational numbers be simplified or reduced to their simplest form? | |
Ans. Rational numbers can be simplified to their simplest form by dividing both the numerator and denominator by their greatest common divisor. This process results in a fraction that cannot be reduced any further, ensuring that the ratio is in its simplest form.
