## Techniques on Subtracting Fractions and Whole Numbers

The video below in mixed Tagalog and English is a tutorial on techniques in subtracting fractions and whole numbers (and vice versa). It discusses the “borrowing technique” which does not need to convert mixed fractions to improper fractions in order to perform the calculation. This technique will save you a lot of time and will lessen the probability of error during calculation.

This video is part of my collection of tagalog or Taglish math tutorials in Sipnayan.com. I believe that Sipnayan will be very useful for elementary school and high school students, so you can share the blog with them.

## How to Subtract Fractions

We have already learned the three operations on fractions namely addition, multiplication, and division. In this post, we are going to learn the last elementary operation: subtraction. If you have mastered addition of fractions, this will not be a problem for you because the process is just the same. Let’s subtract fractions!

Example 1: $\displaystyle \frac{8}{15} - \frac{3}{15}$.

Solution

The given is a similar fraction (fraction whose denominators are the same), so just like in addition, we just perform the operation on the numerators. Therefore, we just have to subtract the numerator and copy the denominator. That is,  Continue Reading
