Simplifying Complex Fractions

The video tutorial explains how to simplify complex fractions, which are fractions with fractions in the numerator and denominator. It covers two methods: the first involves rewriting the complex fraction as a division problem and using the reciprocal to simplify, while the second method uses the least common denominator to simplify the fractions. Both methods ultimately lead to the same simplified expression.

What is a complex fraction?

• A fraction that cannot be simplified.

• A fraction where the numerator and/or denominator are also fractions.

• A fraction with a numerator and denominator that are both integers.

• A fraction with a variable in the denominator.
