Question 210258
{{{-125/5}}} Start with the given expression.



{{{(-25*5)/5}}} Factor -125 into -25*5. Note: -25*5=-125



{{{(-25*cross(5))/cross(5)}}} Cancel out the common factors.



{{{-25}}} Simplify



So {{{-125/5=-25}}}



An alternative is to use long division.


-----------------------------------------


For problem #2, you need to know your multiplication. Also, it turns out that when you multiply two negative numbers, the result is positive. Why? Think of negatives as opposites...ie they 'undo' positive numbers. 



So {{{(-8)(-4)=32}}} 


-----------------------------------------


{{{-36/9}}} Start with the given expression.



{{{(-4*9)/9}}} Factor the numerator.



{{{(-4*cross(9))/cross(9)}}} Cancel out the common factors.



{{{-4}}} Simplify



So {{{-36/9=-4}}}



In this case, if you know your multiplication, you can take note that -9*4=-36 and then work from there.
