# Multiplication of Fractions

After learning addition and subtraction of fractions, we have now learn multiplication of fractions. Multiplication is the easiest operation on fraction, so I think you will enjoy it.

Lesson 1: MF1 Multiplicaiton of Fractions Part 1 (Proper and Improper Fractions)

In this post, we learn how to multiply proper and improper fractions. Multiplying of proper and improer fractions is simple. You multiply all the numerators of the factors and then multiply their denominators. The product of the numerators is equal to the numerator of the resulting product and the product of the denominator is equal to the denominator of the the resulting product.

Lesson 2: MF2 Multiplicaiton of Fractions Part 2 (Mixed Fractions)

In this post, we learn how to multiply mixed fractions. The easiest method to do this is to convert all mixed fractions to improper fractions before multiplying. Once you have done this, you can use the method used in MF1.

Lesson 3: MF3 Multiplicaiton of Fractions Part 3 (Shortcut)

In this post, we learn how to use the cancellation method to multiply fractions. Here, cancellation means dividing both the numerator and the denominator of the fractions being multiplied by the same number.

In the next series, we will learn how to divide fractions.

# MF3 Multiplication of Fractions (Shortcut)

In MF1, we learned how to multiply proper and improper fractions and in MF2, we learned how to multiply mixed fractions. In this post, we are going to learn some shortcut method to help us multiply fractions faster. Some call this technique the cancellation method where you cancel the numerator and the denominator of the fractions being multiplied. Here, cancellation really means dividing both the numerator and the denominator by the same number (much better you divide them by their GCD) to reduce them to a smaller number. This way, multiplication will be easier.  Continue reading

# MF2 Multiplication of Fractions (Mixed Fractions)

In MF1, we have learned how to multiply proper and improper fractions. In this video, we are going to learn how to multiply mixed fractions. The strategy in multiplying fractions is really simple: you have to convert mixed fractions to improper fractions before multiplying. Watch the video above and then answer the exercises below.  Continue reading
