what are the example of quotient orf rational algebraic expression.
A rational algebraic expression is the ratio of two polynomials, each with rational coefficients. By suitable rescaling, both the polynomials can be made to have integer coefficients.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
it can be use in business, office and shopping
an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication,division and exponentiation to a power that is a rational number). For example,
