Rational numbers are numbers that can be expressed in the form of a/b, where a, b are integers and b is not equal to zero. Rational numbers are also called as fractions. Multiplication of fractions is very simple and straight forward. Two multiply two fractions a/b, c/d first multiply both the numerators to arrive at the new numerator. Next multiply both the denominators to arrive at the new denominator. Now the new fraction can be further simplified to arrive at the solution. Note that you actually need not multiply the numerators and denominators directly and then simplify. It is advisable to simplify the fractions first and then multiply to solve the problem easily. This video shows how to multiply rational numbers or fractions.
