a) a/b+c/d=(a+c)/(bd)
This is incorrect (unless b=1 and d=1) because a/bd
does not equal a/b and c/bd does not equal c/d
.
b). a/b+c/d=(a+c)/(b+d)
This is incorrect because you cannot add fractions merely by adding numerators and denominators.

c). a/b+c/d=(ad+bc)/(bd)
This is correct:
ad + bc/ bd = ad + bc/ bd
