To multiply fractions, first convert any mixed fractions to improper fractions. Then, multiply the numerators across to get the answer numerator. Do the same thing for the denominators, multiplying the two values across to get the answer fraction s denominator. Reduce, and if the answer is improper, turn it into a mixed fraction.
A way to address this is to learn how to compare fractions and find common denominators so that two fractions can be numerically compared clearly. The worksheets on this page provide exercises to do exactly that, and they are good practice for the steps necessary for other fraction operations.
Reducing fractions is another skill involved in just about any of the fraction operations. The fraction worksheets on this page introduce reducing gradually by providing problems with increasingly more difficult denominators, and only gradually introducing mixed numbers and improper fractions.
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.
