## Adding and Subtracting Fractions

The steps of adding fractions are .........

Step one : Find the common denominator

Step two : Multiply it so the denominator are the same

Step three : Multiply the numerator so the fraction is still the same

Step four : Add the numerators together

Step five : Write the denominator , don't change it

Step six : Make it the simples form ( divide it )

The steps for subtracting are ......

Step one : Find the common denominator

Step two : Multiply it so the denominators are the same

Step three : Multiply the numerator so the fraction does change

Step four : Subtract the numerator

Step five : Write the denominator , don't change it

Step six : make it the simplest form ( divide it )

## Example

## Equation The problem we are going to solve | ## Finding the same denominator I multiplied by two to get my same denominator | ## Simplest form I changed it to one whole to make it the simplest form |

## Eqation The problem we are going to solve | ## Finding the common denominator I multiplied it by two so I could have the same denominator | ## Changing it to the simplest form I divided by two , two times so it would be the simplest form |

## Dividing Fractions

## Explanation

Step one : Keep the first fraction

Step two : Flip the second fraction

Step three : Now you multiply the numerator

Step four : Multiply the denominator

Step five : Change it to the simplest form ( divide it )

## Example

## Equation The problem we are going to solve | ## Flip it and multiply I flip the second number and then I multiplied it | ## Simplest form I divide it by two to get the simplest form |

## Multiplying Decimals

## Explanation

Step one : write it down like a normal multiplication problem

Step two : multiply like normal

Step three : count how mAny numbers are to the right of the decimal point

Step four count from the right of your answer as many steps you counted before

Step five : you've got your answer
