To simplify the expression -28st over -4s, you can follow these steps:

Step 1: Cancel out the negative signs:
-28st divided by -4s is the same as 28st divided by 4s, since dividing both the numerator and the denominator by -1 cancels out the negatives.

Step 2: Divide the coefficients:
28 divided by 4 is 7.

Step 3: Simplify the variables:
The "t" variable does not have a counterpart in the denominator, so it remains as it is.
The "s" variable in the denominator cancels out with one "s" in the numerator, leaving us with just one "s" in the simplified form.

Putting it all together, the simplified form of -28st over -4s is 7t.
