How do you subtract fractions?

• To subtract fractions, they must have a common denominator. If they do not, find a common denominator, convert the fractions, and then subtract the numerators.

• Simply subtract the numerators and keep the denominators the same.

• Multiply the fractions and then subtract the result from one of the fractions.

• Add the fractions together and then subtract the result from one.
