Answer:
How to Add and Subtract Mixed Numbers By Finding Common Denominators
Step 1: Convert your mixed fractions to improper fractions. To do this, multiply your whole number by the denominator of the fraction. This becomes the numerator of your improper fraction. The denominator stays the same.
Step 2: Rewrite your expression with your improper fractions.
Step 3: Make your denominators the same. To find a common denominator, multiply the top and bottom of your first fraction by the denominator of the second fraction.
Step 4: Next, multiply the top and bottom of your second fraction by the denominator of the first fraction.
Step 5: Now that you have a common denominator, you can perform the indicated operation on the values in the numerator of each fraction. Your denominator should remain unchanged.
