Answer:

The answer is
(13)/(36)

Explanation:

The formula is:


(a)/(b) -  (c)/(d)  =  (ad - bc)/(bd)

In this case :


(12)/(16)  - (7)/(18) =  (12 x 18 - 16x17)/(16x18) = (216 -112 )/(288) = (104)/(288)

To get the simples form notice both 104 and 288 are divisible by 8 and 104/8 = 13 and 288/8 = 36.

Thus
(104)/(288) = (13)/(36)
