What fraction (part) of this hexagon is red?

If you said, "All of it." You are right... But, your answer isn't a fraction.

Improper

Fraction

Actually, there's nothing improper about them... It's just when the numerator is bigger then the denominator.

So, let's see what this means. Let's looks at a hexagon... That's 7 pieces...

                   

Hey, this is just  !

How about  ?

So, let's compute  :

9 goes into 11 once with 2 left over

and here's how we write it all

See how we stick the original denominator under the 2 ?

Let's change    to an improper fraction.

So, 

How to change MIXED NUMBER to Improper Fraction…

Adding Fractions

When the Denominators are the Same

So 

  Let's do one without pictures: Easy!

Adding Fractions

When the Denominators

are Different

Let's try this:

The main rule of this game is that we can't do anything until the denominators are the same!We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.

The LCM of 2 and 3 is 6. So, our LCD 6.

We need to make this our new denominator...

Change the  :

Change the  :

Now we can do it!

What is LCD??

What is LCD??

Multiplying

Let's just do one:

We just multiply straight across...

Reduce it!! Make it simplest!!!

Let’s do this!!!  

is already a fraction... But, what about the 6?

Guess what? We can write 6 as  .

Think about it:

  is the same as  ... which is 6!

(You can do this with any number!)

Back to the problem:

Let's change    to an improper fraction.
