![]() When multiplying fractions, you can cancel (do early simplifying) first, which eliminates the need to simplify your answer later. Write the whole number as a fraction with a denominator of 1. This answer had to be simplified because it wasnt in lowest terms. The first example above is a rational algebraic. To multiply fractions, simply multiply the numerators then multiply the denominators. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. The two parts of the fractions are the denominator. If this is the case, you can skip ahead to the next section. A rational algebraic fraction is an algebraic fraction whose numerator and denominator are both polynomials.
