Frequently Asked Questions
To add or subtract fractions, they must have the same denominator. If they don't, find a common denominator first by multiplying the denominators. Then add or subtract the numerators while keeping the same denominator. Finally, simplify the result if possible.
To multiply fractions, multiply the numerators together and multiply the denominators together. For example, (a/b) × (c/d) = (ac)/(bd). Then simplify the result if possible.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction. For example, (a/b) ÷ (c/d) = (a/b) × (d/c) = (ad)/(bc). Then simplify the result if possible.
A mixed number is a whole number plus a fraction, like 3½. To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator, then put this over the denominator. For example, 3½ = 7/2.
