Front

When adding fractions, what must be the same?

Back

The denominators must be the same before you can add the fractions.

Front

What is the formula for finding the area of a rectangle?

Back

What does it mean to simplify a fraction?

Back

To simplify a fraction means to reduce it to its lowest terms, where the numerator and denominator have no common factors other than 1.
