Learn how to add and subtract mixed numbers. Mixed numbers are numbers with two parts: the whole number part and the fraction part. Mixed numbers are ways to represent improper fractions using proper fractions. To add or subtract mixed numbers, we first convert the mixed numbers to improper fractions by multiplying the whole number with the denominator and adding the result to the numerator, this becomes the new numerator and we retain the original denominator. After we have converted the mixed numbers to improper fraction we can now add or subtract the fractions. Alternatively, we can split the mixed numbers and add the whole number parts separately and the fraction parts separately and then join the results.
