A) 1/12
B) 1/4
C) 1/2
D) 1
E) 2

Question

anonymous · Answer

factor 12....

anonymous · Answer

i think the point is that if t is prime, it is not divisible by 2 or 3 or 6 or 12

anonymous · Answer

so 
$$\frac{t}{x}$$ cannot be 2

anonymous · Answer

I'm not sure how it can be 1/12 either...unless they are counting 1 as a prime (which it's not)

anonymous · Answer

maybe i am wrong though.

anonymous · Answer

ok it certainly could be 1 yes?

anonymous · Answer

I agree with the answer of 2, satellite :)

anonymous · Answer

t=3, x=3 gives you 1
t=2, x=4 gives you 1/2
t=3, x=12 gives you 1/4

That's all I can "prove"

anonymous · Answer

1 is not a prime...

anonymous · Answer

no i meant the ratio could be 1

anonymous · Answer

Ahh...
t=2, x=1 gives you 2!!!

anonymous · Answer

Answer is 1/12

anonymous · Answer

silly me..not thinking about 1 as a factor of 12

anonymous · Answer

yeah well silly me too

anonymous · Answer

$$\frac{t}{x}=\frac{1}{12}$$
$$12t=x$$
not likely

anonymous · Answer

Well, since t > 1, in order for t/x = 1/12, it must be that x > 12.  But since x is a factor of 12, x <= 12.  Which is a contradiction. :)
