How do you subtract fractions?

Make sure the bottom numbers (the denominators) are the same. Subtract the top numbers (the numerators). Put the answer over the same denominator. Simplify the fraction (if needed).

To Subtract Fractions with different denominators:

Find the Lowest Common Denominator (LCD) of the fractions. Rename the fractions to have the LCD. Subtract the numerators of the fractions. The difference will be the numerator and the LCD will be the denominator of the answer. Simplify the Fraction.

How to simplify a fraction:

Find a common factor of the numerator and denominator ... Divide both the numerator and denominator by the common factor. Repeat this process until there are no more common factors. The fraction is simplified when no more common factors exist.
