1 Multiplying Fractions Actually, this is the easiest operation to perform on fractions. Numerator times numerator, denominator times denominator. If you can, try to “cancel” or factor a common factor first then multiply. If there is a mixed number involved, you must change it to improper first. If you get an improper fraction as an answer, change it to a mixed number answer,
