How do you divide fractions?

Back

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. For example, a/b ÷ c/d = a/b × d/c.

Front

What is the reciprocal of a fraction?

Back

The reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of 3/4 is 4/3.

How do you find the total weight of apples in a full bin if you know the weight of apples in a partial bin?

Back

If the bin is 5/9 full and contains 6 1/6 pounds, you can set up a proportion to find the total weight: (6 1/6) / (5/9) = total weight / 1.

What is the formula for finding the volume of a box?

Back

Volume = width × length × height.
