 * __The Background information of our UN-Project:__**

- with "like" denominators - with different denominators - with common denominators - with lowest common denominators - learning how to borrow when subtracting
 * __ADDING AND SUBTRACTING FRACTIONS...__**


 * __ADDING AND SUBTRACTING WITH "LIKE" DENOMINATORS__**

Subtracting number is the same process as adding them. Just remember to simplify.

Try these: 5/6 - 4/6 = 7/10 - 1/10 = 1/7 + 5/7 = 2/8 + 5/8 =

__**ADDING AND SUBTRACTING WITH DIFFERENT DENOMINATORS**__

First make the denominator the same by multiplying the two denominators. Then multiply the numerators by the number you multiplied the denominators by. Then you add the numerators and keep the denoimator. Make it into a mixed fraction


 * __ADDING AND SUBTRACTING WITH COMMON DENOMINATORS__**

So the first thing you do is multiply each denominator by eachother. 5 / 6 + 4 / 5 6 x 5 = 30 30 is the denominator for both. then you multiply the numerators by the same # you multiplied the denominators by. 5 x 5 = 25 4 x 6 = 24 25 / 30 + 24 / 30 add them together and keep the denominator 49 / 30 Then you can make it into a mixed fraction.
 * When your adding fractions always make sure that the denominators are the same.**

just do the same thing you did with the numerators and denominators 25 / 30 - 24 / 30 Then subtract. 25 / 30 - 24 / 30 = 1 / 30
 * When your subtracting always make sure the denominators are the same as well .**


 * __ADDING AND SUBTRACTING WITH LOWEST COMMON DENOMINATORS__**

media type="custom" key="42801"

Subtracting numbers where you have to find the common denominator is the same as adding it.

Here are some questions you can try: 7/8 - 4/4 = 8/9 - 3/6 = 4/10 + 5/6 = 4/6 + 5/7 =


 * __HOW TO BORROW WHEN SUBTRACTING__**

media type="custom" key="42802"

Here are some questions you can try for you yourself. 1 1/5 - 3/5 = 5 4/6 - 1 8/7 = 3 2/3 - 3/9 =
