If r and s are positive integers, is r/s an integer?
(1) Every factor of s is also a factor of r.
(2) Every prime factor of s is also a prime factor of r.
This question is relatively straightforward
St 1
Every factor of s in also a factor of r- this means that every factor of s must be a factor of r- so in other words s must be the same size as r -neither can be larger
St 2
2 x3 /3 x 2 x 2 this satisfies the condition but is obviously not an integer so insufficient
