f/-11 < 9

To determine if the inequality f/-11 < 9 is true or false, we need to perform some calculations.

Let's start by multiplying both sides of the inequality by -11 to get rid of the fraction:

f < 9 * -11

Now we can simplify the multiplication:

f < -99

The inequality states that f is less than -99. If a number is less than -99, it is true that f/-11 is less than 9.

So, the original inequality f/-11 < 9 is true when f is less than -99.
