## What is a rational expression example?

In other words, we can say a rational number is nothing more than a fraction in which the numerator and the denominator are integers. Examples of rational expression are 5/x − 2, 4/(x + 1), (x + 5)/5, (x2 + 5x + 4)/(x + 5), (x + 1)/(x + 2), (x2 + x + 1)/2x etc.

## What does a rational expression look like?

A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions. The last one may look a little strange since it is more commonly written 4×2+6x−10 4 x 2 + 6 x − 10 .

## How do you identify a rational expression?

Rational expressions are fractions containing polynomials. They can be simplified much like numeric fractions. To simplify a rational expression, first determine common factors of the numerator and denominator, and then remove them by rewriting them as expressions equal to 1.

## What are 5 examples of rational numbers?

Examples of Rational Numbers
5 You can express 5 as 51 which is the quotient of the integer 5 and 1.
2 You can express 2 as 21 which is the quotient of the integer 2 and 1.
√9 Is rational because you can simplify the square root to 3 which is the quotient of the integer 3 and 1.

## What are 10 examples of rational?

If a number is expressed in the form of p/q then it is a rational number. Here p and q are integers, and q is not equal to 0. A rational number should have a numerator and denominator. Examples: 10/2, 30/3, 100/5.

## What are 3 examples of rational numbers?

Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, –3/4, 0.3, or 3/10.
