help with this one?

-15-5=help With This One?

Answers

Answer 1

Answer:

The answer is 3.

Step-by-step explanation:

If you divide a negative by a negative, then it equals a positive, because the two negatives cancel out.

So, -15/-5 = 3.

But, if it were -15/5 = ?

Then it would be -3, because there is only one negative, therefore it cannot cancel out.

Hope this helps! :)
