How do you add fractions with the same denominator?

Back

Add the numerators and keep the denominator the same. Example: 1/4 + 2/4 = (1+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. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.

Front

How do you subtract fractions with the same denominator?

Back

Subtract the numerators and keep the denominator the same. Example: 3/5 - 1/5 = (3-1)/5 = 2/5.

Front

How do you subtract fractions with different denominators?

Back

Find a common denominator, convert the fractions, then subtract the numerators. Example: 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2.

Front

What is the process for multiplying fractions?

Back

Multiply the numerators together and the denominators together. Example: 2/3 * 3/4 = (2*3)/(3*4) = 6/12 = 1/2.

Front
