What is a rational number?

A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero. In other words, a rational number can be written in the form of p/q, where p and q are integers and q is not equal to zero. Examples of rational numbers include 1/2, 5/3, and -4/7.

How are rational numbers different from irrational numbers?

Rational numbers can be expressed as fractions of two integers, while irrational numbers cannot be expressed as fractions and have non-repeating, non-terminating decimal representations. In other words, rational numbers include integers, fractions, and decimals that either terminate or repeat, while irrational numbers have decimals that go on forever without repeating.

Can a fraction be considered a rational number?

Yes, a fraction can be considered a rational number because a rational number is any number that can be expressed as a ratio of two integers, where the denominator is not zero. Since fractions are represented as one integer divided by another integer, they fit the definition of a rational number.

Are whole numbers considered rational numbers?

Yes, whole numbers are considered rational numbers because they can be expressed as a fraction where the denominator is 1. Rational numbers include all integers, fractions, and terminating or repeating decimals. Since whole numbers fall under the category of integers, they are classified as rational numbers.

Is zero a rational number?

Yes, zero is a rational number because it can be expressed as a fraction where the numerator is 0 and the denominator is any non-zero integer, such as 0/1. Rational numbers are numbers that can be expressed as a fraction of two integers.

Can rational numbers be negative?

Yes, rational numbers can be negative. Rational numbers include both positive and negative numbers that can be written as a fraction of two integers, where the numerator and denominator are not equal to zero. This means that rational numbers can take on any value along the number line, including negative values.

Are integers considered rational numbers?

Yes, integers are considered rational numbers because they can be expressed as a fraction where the denominator is 1. Rational numbers include integers, fractions, and terminating or repeating decimals, all of which can be expressed as a ratio of two integers.

How do you identify if a decimal is rational?

A decimal is rational if it can be expressed as a fraction of two integers. To identify if a decimal is rational, you would need to determine if the decimal can be written as a fraction in the form a/b, where a and b are integers and b is not equal to zero. If such a fraction can be found that equals the given decimal, then the decimal is rational.

Can rational numbers be expressed as repeating decimals?

Yes, rational numbers can be expressed as repeating decimals. A rational number is a number that can be expressed as a ratio of two integers, such as 3/7 or -5/4. When these numbers are divided, the resulting decimal can either terminate or repeat in a pattern. For example, 3/7 as a decimal is 0.428571428571..., with the digits 428571 repeating indefinitely.

How can you perform operations, such as addition or multiplication, with rational numbers?

To perform operations like addition or multiplication with rational numbers, simply treat them like regular fractions. For addition, find a common denominator if needed, add the numerators together, and keep the denominator the same. For multiplication, multiply the numerators together to get the new numerator, and the denominators together for the new denominator. Reduce the resulting fraction to its simplest form if necessary.
