What is a rational number?

A rational number is a number that can be expressed as the quotient or fraction p/q, where p and q are integers and q is not equal to zero. Rational numbers can be finite decimals or repeating decimals, and they can be positive, negative, or zero.

Give an example of a rational number.

One example of a rational number is 3/4. This fraction represents the division of 3 by 4, where 3 is the numerator and 4 is the denominator, and it can be expressed as a finite decimal, 0.75.

How can rational numbers be expressed?

Rational numbers can be expressed as the quotient of two integers, where the denominator is not zero. They can be written in fraction form as a/b, where a and b are integers and b is not equal to zero. Additionally, rational numbers can also be represented as decimals that either terminate (e.g., 0.75) or repeat (e.g., 0.3333...). Overall, rational numbers can be expressed in various forms that highlight their relationship to integers.

Is the sum of two rational numbers always rational?

Yes, the sum of two rational numbers is always rational. This is because rational numbers are numbers that can be expressed as a ratio of two integers, and when you add or subtract two rational numbers, the result can also be expressed as a ratio of two integers, making it a rational number as well.

What is an irrational number?

An irrational number is a real number that cannot be expressed as a simple fraction or ratio of two integers. This means that its decimal representation goes on infinitely without repeating. Examples of irrational numbers include the square root of 2, pi, and the Golden Ratio.

Give an example of an irrational number.

One example of an irrational number is the mathematical constant pi (?), which represents the ratio of a circle's circumference to its diameter. Pi is a never-ending, non-repeating decimal, making it an irrational number.

Can irrational numbers be expressed as a fraction?

No, irrational numbers cannot be expressed as a fraction. Irrational numbers are numbers that cannot be written as a simple fraction of two integers and have non-repeating, non-terminating decimal expansions. decimals. Examples of irrational numbers include ?2, ?, and e.

Is the product of two irrational numbers always irrational?

No, the product of two irrational numbers can sometimes be rational. For example, the product of ?2 and ?2 is 2, which is a rational number. However, in general, it is not guaranteed that the product of two irrational numbers will be irrational.

Explain the difference between rational and irrational numbers.

Rational numbers are numbers that can be expressed as a ratio or fraction of two integers, such as 2/3 or -4/5. Irrational numbers, on the other hand, cannot be expressed as a simple fraction and have non-repeating, non-terminating decimal representations, like the square root of 2 or pi. In summary, rational numbers can be written as fractions, while irrational numbers cannot and have decimal expansions that go on forever without repeating.

Give a real-life example of a rational and an irrational number.

A real-life example of a rational number would be the price of a movie ticket, such as $6.50. This is rational because it can be expressed as a ratio of two integers (13/2) and can be exactly represented as a finite decimal. An example of an irrational number would be the value of pi (?), which is approximately 3.14159. This is irrational because it cannot be expressed as a ratio of two integers and has an infinite, non-repeating decimal expansion.
