Recognizing a fraction when you see one is easy. Fractions represent part of a whole number. But not all fractions are the same type. Proper fractions have top numbers, or numerators, lower than their bottom numbers, or denominators. Improper fractions are those where the numerators are bigger than the denominators. Another way to write improper fractions is as mixed numbers where units are shown next to a proper fraction. For example, 43 is the equivalent of 113.

Take this quiz and test your knowledge of fractions.
