Solve the equation -12 = f/0.2 (Thats a fraction)
Shalnov [3]
-12 = f/0.2

First, we can start out by making our goal to get the variable (f) on one side of the problem by itself. To do this, multiply both sides by 0.2. 
-12 \times 0.2 = f

Second, our next step is to multiply -12 times 0.2. This can be solved in your head, on a piece of paper, on a calculator, etc. (-12 times 0.2 = 2.4).
-2.4 = f

Third, our last step will be to switch sides. Basically flip the problem.
f = -2.4

Answer: \fbox {x = -2.4}
