Add and Subtract Fractions with the Same Denominators

In this activity, we'll be tackling the topic of adding and subtracting fractions with the same denominators.

 

When adding fractions with the same denominator, we simply add the numerators. 

 

So, 2/8 + 4/8 = 6/8

 

When subtracting fractions with the same denominator, we simply find the difference between the numerators. 

 

So, 6/8 - 4/8 = 2/8

 

Did you spot that the denominators stay exactly the same?

We don't change these. 

 

 

Let's try an example together.

 

Example

 

 

Answer

First, we add together the numerators.

2 + 4 = 6

 

Remember we leave the denominators as they are.

 

 

Pretty simple right?

Now it's over to you to try some questions like this.

 

Good luck!
