if the denominators are the same, simply add the minuend. so if you got 1/4 + 1/4 = 2/4 and just simplify to get 1/2.
if the denominators are not the same, lets say 1/2 + 1/3, get the LCD of 2 and 3, which is 6.
divide LCD by the denominator and multiply the answer by the minuend. so 6/2 = 3 + 1 = 4. 4 will be the new minuend and the lcd will be the new denominator. then you will get 4/6. Get the other fraction. then add them. then simplify.
gud luck

1. Times the denominators by each other.
2. Times the number at the top with the number you used to times the bottom.
3. Add the numerators together.
4. Simplify

if ur adding say 3/4 plus 1/3, u multiple each side by the bottom number of the other number, like 3/4 times 3/3 which would make it 9/12 and the the other one 1/3 times 4/4 which would make it 4/12 then just as 9/12 and 4/12.

find the lowest common denominator by multiplying the 2 denom numbers (the bottom numbers) and multiply the top numbers accordingly...then add the top, bring the same on the bottom, and reduce.

Get a common denominator.

you should find the LCM (least common denominator) then add.
