__Adding Fractions__
When you're adding fractions, the denominators must be the same in each fraction.
 * example:** 2/4 + 3/4

If the denominators are different, you need to convert it so that they are the same. example: 3/5 + 1/3 To do this you need to: A multiple of 5 and 3 is 15, which will be the denominator of the two converted fractions. ?/15 + ?/15 The first fraction is 3/5, so now it will be 9/15 because we multiplied the original denominator by 3, so we also need to do that to the numerator. Denominator is 15 (5 x 3) Numerator is 9 (3 x 3) 9/15 + ?/15 3 x 5 = 15 <denominator 1 x 5 = 5 <numerator 9/15 + 5/15 9/15 + 5/15 = 13/15
 * __How to add fractions with different denominators__**
 * 1. Find the common denominator (a multiple of the denominators of two or more fractions).**
 * 2. Now for the numerators, you don't just leave it you need to covert it also.**
 * 3. We also need to do the same thing with the second fraction's numerator.**
 * 4. Now once the fractions are converted, you simply add the numerators together and keep the denominator.**

Adding mixed fractions are very simple if you remember the steps. -when adding mixed fraction you always change it to a proper fraction. 2) The answer from step 1 plus the numerator from the original mixed fraction.** example: 3 2/4 + 2 1/4 = 5 3/4 or 23/4 4x3+2=14/4 4x2+1=9/4 14/4 + 9/4= 23/4 14+9=23
 * __How to add mixed fractions__**
 * 1) You multiply the denominator with the whole number.
 * 3)Now it's a matter of just adding the two fractions together.**

To get an improper to a proper fraction you just have to follow these steps: 2) find the remaining number of parts 3) put the number of parts remaining as a numerator.** example: 17/5 + 11/5 = 28/5 Or 25 3/5 (the denominator always stays the same)
 * __How to add improper fractions__**
 * 1) determine the number of time the denominator goes into the numerator.
 * 4) If you get two improper fractions then it's a matter of adding the numerators together and the denominators.**

__Subtracting Fractions__
-to subtract fractions, you must make sure the denominators of all of the fractions are the same. example: 2/4 -2/8 (they are not the same) example: 2/8 - 2/8 (they are the same)

-if your denominators of the fractions are not the same then you have to find it's lowest common denominator. -when your denominators are the same you subtract only the numerators. example: 5/8 - 2/4 = ?/? It's the same thing as adding fractions but then you just have to subtract the numbers. example: 4 6/8 - 3 2/8 = 1 4/8 or 1 1/2. It's the same thing as adding fractions, but now you just have to subtract. example: 48/10 - 25/10 = 23/10 or 2 3/10
 * __How to subtract mixed fractions:__**
 * __How to subtract improper fractions:__**

You have to add the numerators first and you leave the denominator. example: 18/35 + 15/35 = 33/35 You have to subtract the numerators first and you leave the denominator. example: 48/55 - 27/55 = 21/55
