Subtracting Fractions


Subtracting fractions is done by an identical process to adding fractions until the final step of subtraction.

Before continuing, ensure your child understands the concept of subtraction and that they are confident in subtracting whole numbers.

Subraction - a quick review.

Subtraction is simply the removal of one set of objects from another set, resulting in a new total.

2 - 1 = 1
Two whole numbers minus one whole number equals one whole number
Two apples minus One apple equals One apple
Two apples minus One banana equals Two apples minus One banana
This cannot be done as you cannont subtract different objects. Read on to see how you would deal with this problem
In my section on adding fractions, I discussed the different ways to verbalize a fraction, and concluded that the only way a student should b e referring to fractions now, is by eactly what they are.

1/2 is "One Half"; 1/4 is "One Quarter" 9/8 is "Nine Eights". The reason for this is so that when they see a problem like:

fraction subtraction<br><br>

They will say
And when they see a problem like:

fraction subtraction<br><br>

They will say equivalent fractions by finding the common denominator!"

I have created a seperate section devoted to finding the common denominator, but for now, here is the math fact that works for all fractions, all the time.
