Is 1.45 rational or irrational?
It is a rational number because it can be expressed as a fraction
How polynomial expression is a rational expression?
A polynomial expression is considered a rational expression when it is expressed as a fraction where both the numerator and the denominator are polynomials. For example, the expression ( \frac{x^2 + 3x + 2}{x - 1} ) is a rational expression because its numerator ( x^2 + 3x + 2 ) and denominator ( x - 1 ) are both polynomials. Rational expressions can be simplified, added, or multiplied, just like rational numbers, provided that the denominator is not zero.
Is 5.85 a rational number?
Yes, 5.85 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers, and the denominator is not zero. In this case, 5.85 can be expressed as the fraction 585/100, where both the numerator and denominator are integers. Therefore, 5.85 is a rational number.

How are simplifying algebraic expressions similar to simplifying rational expressions?
Simplifying algebraic expressions and simplifying rational expressions both involve reducing the expression to its simplest form by eliminating unnecessary terms or factors. In both cases, you combine like terms and apply properties of operations. For rational expressions, this additionally includes factoring the numerator and denominator to cancel common factors. Ultimately, the goal in both processes is to make the expression easier to work with.
How do you reduce rational number to standard form?
To reduce a rational number to standard form, first identify the numerator and denominator. Then, find the greatest common divisor (GCD) of both numbers. Divide both the numerator and the denominator by their GCD to simplify the fraction. Ensure that the denominator is positive; if it's negative, multiply both the numerator and denominator by -1.
The first step in reducing a rational expression is to both the numerator and denominator?
factor
What fraction having rational expression in its numerator or denominator or both?
If you divide a rational expression by another rational expression, you will again get a rational expression.
Is 5.123 rational or irrational?
