Get the LCD of the two fractions and divide the first fraction to the original fraction and multiply it to the numerator then do it to the second fraction then add the numerator of the fractions,simplify if possible.
EX:2/3+2/4
LCD=12
12÷3×2=8
12÷4×2=6
8/12+6/12=14/12
or 1 2/12 or 1 1/6.
That's my answer!
