About Subtracting Mixed Numbers

Subtracting mixed numbers with different denominators involves several steps. First, convert the mixed numbers into improper fractions. To do this, multiply the whole number by the denominator and add the numerator, placing the result over the original denominator. Once both mixed numbers are improper fractions, find a common denominator. The least common multiple (LCM) of the denominators is usually the easiest common denominator to work with. Convert each fraction to have this common denominator. After the denominators are the same, subtract the numerators. Finally, simplify the resulting fraction and convert it back to a mixed number if needed. This tool simplifies this process for you!
