Explanation:

Step1: Evaluate first statement

Adding/subtracting fractions requires equal denominators to combine parts of the same size. So "You have to have common denominators to add or subtract fractions?" is True.

Step2: Evaluate second statement

A common denominator is a multiple of denominators (e.g., LCM), not their sum. So "To find a common denominator you add them together." is False.

Answer:

True, False
