Multiplying Fractions
For example, when you multiply 3 x 4, you could make a model that is 3 across and 4 down.
We can use the same sort of model to multiply fractions. If you have proper fractions, you will need to start with a unit square.
Check out this example:
So let's see what happened mathematically.
When we multiply fractions, we multiply the numerators and then we multiply the denominators.
We can use this as our algorithm to multiply fractions.
Example 1:
Multiply the tops. Then multiply the bottoms.
Example 2:
We will follow the same steps again.
Example 3:
In this example, we get an improper fraction. We can rewrite this as a mixed number.
Example:
We can even use this method to multiply a fraction with a whole number. The key is to write the whole number as a fraction first. 4 becomes 4 over 1. 8 becomes 8 over 1.
We can even use this method to multiply a fraction with a whole number. The key is to write the whole number as a fraction first. 4 becomes 4 over 1. 8 becomes 8 over 1.
Now we can change the improper fraction to a mixed number to show our answer.
So let's review.
To multiply fractions, you simply need to multiply the numerators and then multiply the denominators. Finally, write your answer as a fraction.
