It is dividing by 3
Inverse means opposite so division is the opposite of multiplacation
cross-multiplying
Well, for a product, you would be multiplying. So 19 and it's opposite, -19, you would multiply them to get a product of -361.

There is no difference in the procedure.

cross-multiplying
The opposite of doubling a number is halving it. This is also known as multiplying by 1/2 or .5 or dividing by 2.
what multiplying factor decrease a number by 3 %

When you divide by a fraction, you are multiplying by it's reciprocal or opposite. So if you are dividing by 1/2, it is the same thing as multiplying by 2/1.
-3 x -3=9 A rule in pre-algebra summarizes in a problem when their is an odd amount of odd - (negative numbers) then the answer is negative, if it is even is is positive.So the problem is asking, the opposite of three times the opposite of three equals 9, so lets take one of those opposites away. The opposite of three times three equals opposite of nine. (If you haven't noticed, negative and opposite are interchangeable.) And another opposite and get the original problem, the opposite of three times the opposite of three equals 9. So the opposite of the negative nine from the first multiply, is positive nine.Example-3 x 3= -9 (1 negative)-3 x -3= 9 (2 negative, the opposite of the opposite.)Tips- It is easier to think as two - - = +,DO NOT MISTAKE THIS WITH ++=+, IT DOES NOT EQUAL A NEGATIVE.THIS ONLY WORKS WITH MULTIPLYING AND DIVIDING.(in basic math)
Multiplying by -1/3
The inverse would be dividing because thats the opposite of multiplying.
