Hey guys,

I dont think d and c Need to be a fraction.

1 - c/d > 0

c/d 0

Since d is positive, we can multiply both sides by d without changing the sign.

Therefore c>0

Condition 1 fulfilled.

Now For condition 3:

If c=5 and d=6

The two conditions above are fulfilled as so is this condition

BUT

If c=1/3 and d=1/2

Again the two conditions are fulfilled but not this one.

Thus only conditions 1 and 2 MUST be true.
