If m and n are positive integers is m/n an integer?

(1) m is a multiple of 14
(2) n is a divisor of 14

how c is the answer ?

say m =14, n=28.
m/n=1/2, am i missing anything?

The statement 2 was n is divisor of 14 it means 14,7,2,1 u considered it a multiple of 14 so u got fraction ..

ex m = 14 * a and n= 14/ a where a is a positive number m/n gives you a^2 ..SO u get an integer I hope u got it ! :-D

If \(m\) and \(n\) are positive integers is \(\frac{m}{n}\) an integer?

(1) \(m\) is a multiple of 14. Not sufficient as no info about \(n\).

(2) \(n\) is a divisor of 14. Not sufficient as no info about \(m\).

(1)+(2) As from (2) \(n\) is a divisor of 14 then it must be a divisor of every multiple of 14, therefore it's a divisor of \(m\) too. Sufficient.

Answer: C.

This question asks is m a multiple of "n"?

St 1

M is a multiple of 14- obviously insufficient no info about n - we just know

M/ 7 x 2 = some integer X therefore M= 7 x 2 x K (some integer)

St 2

N is a divisor of 14 just means N is a factor of 14- obiously insuff no info about M

St 1 and St 2

7 x 2 x k/ any factor of 14 = integer

7 x 2 x k / 14 = integer for example as Bunuel explained
