How do I invert fractions?

To invert a fraction simply means to turn it upside down. Place the denominator where the numerator is and place the numerator where the denominator is.

Fractions have two parts: the numerator and denominator. The numerator is the top number, and the bottom number is the denominator. When you invert a fraction, you simply switch the places of the numerator and the denominator. For example, If you have the fraction 3/7 and then invert it, you have 7/3.
