Answer 2

To solve the equation -40/x = -2 1/2, you can start by converting the mixed number -2 1/2 into an improper fraction. -2 1/2 is the same as -5/2.

So the equation becomes:

-40/x = -5/2

Now, you can solve for x by multiplying both sides of the equation by x to isolate x:

-40 = (-5/2) * x

To get rid of the fraction on the right side, you can multiply both sides of the equation by the reciprocal of -5/2, which is -2/5:

(-40) * (-2/5) = x

Now, perform the multiplication:

x = (40 * 2) / 5

x = 80/5

x = 16

So, the solution to the equation -40/x = -2 1/2 is x = 16.
