SOLUTION: Each figure represents a Real Number and no denominators are zero. Choose the correct statement and briefly explain why the others are not correct. a) a/b+c/d=(a+c)/(bd)

Question 1005494: Each figure represents a Real Number and no denominators are zero. Choose the correct statement and briefly explain why the others are not correct.

a) a/b+c/d=(a+c)/(bd)

b). a/b+c/d=(a+c)/(b+d)

c). a/b+c/d=(ad+bc)/(bd)

Answer by macston(5194) (Show Source): You can put this solution on YOUR website!
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:
