How to Simplify complex fractions in math

In this tutorial the instructor shows how to simplify complex fractions. A complex fraction is the same as a normal fraction, but has a fraction problem in the numerator and a fraction problem in the denominator. The first thing to do is arrive at a simple fraction both in the numerator and the denominator. To do this take the lcm of the denominators of the fractions in the numerator and simplify it. Similarly do this in the denominator. Now both the numerator and the denominator have a simple fraction. A fraction is nothing but a division of the numerator by the denominator, so convert this division into multiplication by multiplying the numerator with the inverse of the denominator and simplify it to get the result. This video shows how to simplify complex fractions.
