a, b, c, and d are positive integers where a is divisible by b and c is divisible by d. Which of the following is NOT necessarily an integer? Choose the correct choice from the following options
A) (ac)/(bd) B) a/b + c/d C) (a + c)/(b + d) D) (abc)/d E) (acd)/b
As per the question, let a = 10, b = 5, c = 6, and d = 2. Plugging these into the answer choices, only (a + c)/(b + d) does not yield an integer.
