You add the numerators and put over the denominator.

No.

Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes

You first add the numerators then take the denominator to the bottom of the sum of the numerators.

no.

Yes

add half the denominator to the numerator

multiply the denominator by the whole number, then add the numerator, the denominator is the same as the mixed numbers denominator

You must find a common denominator. You figure out the smallest number that all of your denominators are divisible by. If you have to multiply the denominators by 2, you must multiply the numerators by 2, then add the numerators together, and write above the common denominator. If you have to multiply one denominator to equal the other denominator, then you must multiply the numerator above that denominator, and finally add up the numerators and place above the common denominator. Then reduce the answer to its smallest fraction.

find a common denominator for all three and then add all of the numerators together and keep the same denominator

You add or subtract only the numerators

Just add the numerators and copy the denominator.

seeing as both the numerator and the denominator are the same you simple just add the numerators then the denominator then that your answer.

Just add the fractions, and divide by 2. Before adding, you have to convert to a common denominator; in this case, you can use "4" as the common denominator.Just add the fractions, and divide by 2.

A common denominator is 32.

To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.

Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.

Yes.

if it has a denominator

Yes, you do.

A common denominator is required to add or subtract fractions and not otherwise.

When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.

numerators you add, denominators you leave it the same

Just add the numerators together but the denominator remains the same

you add it to the coeficent then multipy the denominator
