How do you subtract fractions with the same denominator?

Back

To subtract fractions with the same denominator, subtract the numerators and keep the denominator the same. For example, 3/8 - 1/8 = (3-1)/8 = 2/8 = 1/4.

How do you add fractions with different denominators?

Back

To add fractions with different denominators, find a common denominator, convert the fractions, and then add the numerators. For example, 1/4 + 1/3 = 3/12 + 4/12 = 7/12.

What is the process to convert a mixed number to an improper fraction?

Back
