What is a mixed number?

How do you add fractions with the same denominator?

Back

Add the numerators and keep the denominator the same. For example, 1/4 + 2/4 = 3/4.

Front

How do you add fractions with different denominators?

Back

Find a common denominator, convert the fractions, then add the numerators. For example, 1/2 + 1/3 = 3/6 + 2/6 = 5/6.

Front

What is a common denominator?

Back

A common denominator is a number that is a multiple of the denominators of two or more fractions.

Front

How do you subtract fractions?
