Multiplying Fractions

So did you find the CSC Reviewer adding and subtracting fractions easy? Well, you’re in for a treat as multiplying fractions is also as easy as reciting the English Alphabet. As long as you know basic multiplication, this process is a piece of cake. All we have to do is multiply both the numerators and denominators and we’re done. Unless of course if the answer can be converted to its lowest term, do so to get the final answer. Check out the sample equation below.

34 × 12

It is very easy because all we have to do is multiply the top numbers (numerators) and multiply the bottom numbers (denominators) like so;

Here’s another example;

712 × 89 = 56108

 

7 x 8 is 56 and 12 x 9 is 108. This time, the answer can be simplified so our FINAL answer will be 1427. If you forgot how to simplify fractions, then I suggest you watch the video below. You will need to know this process as it is another valuable piece of knowledge to help you pass the Civil Service Exam with a bit of ease.

 

One more example before we proceed to some exercises about the multiplication of fractions;

23 × 54 × 3⁄8

As you can see, the sample above has three fractions multiplied together. Also, the middle one is an improper fraction. Can we still use the same procedure for these kinds of equations? YEP, all we have to do is multiply all the numerators together as well as all the denominators and we’ll have our answer. The process also works no matter how many fractions, proper or improper, are involved.

 

Easy Fraction Multiplication

So that is the process and we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 6:

30/96 = (30 ÷ 6) / (96 ÷ 6), we’ll end up with 516.

And there you have it. I told you multiplying fractions is not that hard. In fact, it is much easier than adding and subtracting fractions. With that said, the test exercises below won’t have multiple choices. Try and solve them manually because they will help you get better at solving these kinds of equations. Again, do not forget to write your answers on a sheet of paper (simplify if necessary or convert to mixed fractions) so you can check it afterward.
