# FRACTIONS

### By Brink

For example let's take the fractions 1/2 and 2/4.

Step 1: make the 2 denominators the the same that would be 2/4 and 2/4.

Step 2: now add 2/4 + 2/4 = 4/4 = 1 whole.

## Subtraction

This is similar to adding but it's just with minus let's take 3/4 and 1/2.

Step 1: make the denominators the same that would be 3/4 and 2/4.

Step 2: now subtract the fractions 3/4-2/4=1/4.

## Sultiply fractions

This is easy very easy.

So lets take 1/4 x 1/2 as example.

All you do is multiply across.

That is equal to 1/8.

Under this is a video so you can remember it.

## Dividing fractions

Dividing fractions is easy as well.

Let take 3/4:1/2 as an example.

You keep the first fraction then you change to multiplication and flip the other fraction.

Then you multiply across.

3/4 x 2/1

That is equal to 6/4 but you can simplify so.

Lets do that and that is 1 2/4 and your done.

To remember their is a video and it is fun.

## Multiplying decimals

Multiplying decimals is easy. It's like regular multiplication.

So lets take 3.2 x 2.4 as an example.

First multiply without the decimal point 32 x 24 =768.

Now you have to put the decimal point back.

So count the digits behind the decimal and that is two.

So put the decimal point 2 spaces to the left from the last digit.

In this case the answer is 7.68

## Dividing decimals

This is easy.

So let's take 12.4 : 3.1 as an example.

First you take away the decimals.Then we get the numbers 124 and 31.

Then you divide 124:31=4. There is no decimal that we have to put back so are answer is 4
