In this video the instructor shows how to simplify a complex fraction. A complex fraction is a fraction that has fractions in both the numerator and the denominator of the original fraction. Complex fractions can look intimidating but are generally simple to solve, as shown in this video. A fraction is nothing but a division of its numerator and its denominator. So in a complex fraction basically you are dividing two fractions. Now you can turn this division into multiplication by multiplying the numerator with the reciprocal of the denominator. Now cancel the common factors in the numerator and the denominator to arrive at the simple fraction, which is the simplified form of the original fraction.
