Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
I think the answer is E even if the first part is (a/b)(d/e)(c/f), because even if (b/d)*(c/e) cancels out,
In stat 2, we don't know if f is a negative number and a is a positive thus we cannot determine the inequality. If the question states that a,b,c,d,e,f are all positive or all negative then the answer is B.
