If r and s are positive integers, is r/s an integer?

1. Every factor of s is also factor of r

2. Every prime factor of s is also a prime factor of r

For statement 2, could you please explain your approach in detail. Thanks!

SUPPOSE r = 30

PRIME FACTORS = 2, 3, and 5

SUPPOSE s = 120

PRIME FACTORS = 2, 3, and 5

but r is not divisible by s or r/s is not an integer.

so A.

From your example given it doesnt look like r/s is an integer and hence answer should be A?? Can you please confirm ....

From st1 does that mean if there are two 2's in r then there should be two 2's in s as well?
