Answer:
-18
Explanation:
Let's break it up into two different equations to start.
First we have 0.75 * -12.
This can be written as 3/4 * 12 as well if you prefer fractions.
This gives us -9.
Now for the second equation.
-6/(2/3)
This can be written as -6/(0.6666....) if you prefer decimals.
Solving this gives us -9.
Now putting the two answers together we have -9 - (-9).
Solving this gives us an answer of -18.
