Subtracting fractions is similar to adding fractions. Most of the work involves the denominator. If the denominators of the two fractions are already the same, much of the work is done. Simply subtract the two numerators to get the answer fraction using the same denominator, and then reduce and make a proper fraction.
If you have mastered adding and subtracting fractions, often multiplying fractions will seem a lot less complicated. Many of the steps feel similar, but much of the work associated with common denominators is gone. However, multiplying fractions will put your reducing skills to the test! If you need more help, the fraction calculator at the link below is a powerful tool for seeing how fraction multiplication problems work.
In the simplest cases, the two fractions will already have a common denominator. In this case, add the numerators and then reduce the resulting fraction.
If the two values being subtracted are mixed fractions, it is often easier to turn them into improper fractions to perform the subtraction. This avoids any kind regrouping or borrowing from the minuend fraction if the numerator in the subtrahend is larger.
