This can be done by identifying the least common multiple of the two denominators. After rewriting the fractions so they both have the common denominator, you can subtract the numerators as you would with any two fractions. video https://cdn.kastatic.org/googleusercontent/bXhENKEsU2-HJYbsZd2b6Ft3n_R060Q01MPUr3QKFY85ubU1Q6N5weJBzV4jJDcyXxXJtBUYZ3Z8wkbhdHitPcVN6Q Subtracting fractions with unlike denominators To subtract fractions with different denominators, you need to find a common denominator.

First, multiply the whole number by the denominator and add the numerator to get the improper fraction. Find a common denominator and adjust the numerators accordingly. Subtract the two improper fractions, and simplify the result if possible. Finally, convert the improper fraction back to a mixed number if desired Sal Khan video https://cdn.kastatic.org/ka_thumbnails_cache/8f5f21f3-fc39-4e9d-903a-0fa5a62f54d4_1280_720_base.png Subtracting mixed numbers: 7 6/9 - 3 2/5 We can subtract two mixed numbers, by converting them to improper fractions.

If the fractions have different denominators, find a common denominator and convert them accordingly. If the fraction on the bottom is larger, regroup by borrowing from the whole number on top. This will allow you to complete the subtraction. video https://cdn.kastatic.org/googleusercontent/zpt7DSKOEW8mXLfiVwpNKu5Bf2BIXhneXm4DGZiR7OeGRKy2NmW_K2i7ZUGgGVa1R8-Dd7SsrgteeV2IyyioRrZv5g Subtracting mixed numbers with regrouping (unlike denominators) To subtract mixed numbers, first align the whole numbers and fractions so they can be subtracted separately.
