Here is the background of what our UN-Project is going to be like: - adding & subtracting fractions - fractions w/ "like" denominators - fractions w/ different denominators - fractions w/ common denominators - fractions w/ lowest common denominators - you will have to know how to borrow when subtracting

=//__**Adding Fractions with "like", different, common and**__//= =//__**lowest common denominators**__//:=

media type="custom" key="36391" = =

=**//__Subtracting with "like" denominators:__//**=

- Just subtract the numerators. - Keep the same denominator.

Here is an illustration:
media type="custom" key="35816" = =

=__**//Subtracting with "unlike" denominators://**__=

- First, find the common denominator. Preferably the lowest common denominator. - Since the denominators are the same, you can subtract the fractions like the way showed above.

//Common Denominator:// Common Denominator is when you have fractions with the same denominator.Is when you have a denominator that fits in two different fractions. You could get this by multiplying the denominator of one fraction to the other numerator and denominator and vice versa.

Here is an illustration:

media type="custom" key="35818"

=**__//Lowest Common Denominator://__**= Is the lowest common (same) factors of two or more numbers. You can get it by multiplying the denominators. Or if the denominators are multiples than you multiply the lower denominator with a number to get the same denominator of the other fractions.

Here is an illustration:
