Comment
The simple answer is you should put something equivalent to -2/5 in the blank. This is what will happen,
-5 * - 2/5
The 5's will cancel out. The minus sign that was in front of the 5 will become positive because 2 minuses make a plus.
Another way to do the problem is to call the ___ = x
-5 x = 2 Divide both sides by - 5
-5x/ -5 = 2/-5
x = - 2/5
It comes to the same thing.
A third way is just to multiply by - 0.4
-5 * -0.4 = 2
