It is dividing by 3
Inverse means opposite so division is the opposite of multiplacation
The opposite of multiplying by 4 is dividing by 4. When you divide a number by 4, you essentially reverse the effect of multiplying that number by 4. For example, if you multiply 8 by 4 to get 32, dividing 32 by 4 brings you back to 8.
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.
multiplied
Try opposite of multiplying Over. For example, 21 over 3 or 21/3 is equal to 7
Inverse means opposite so division is the opposite of multiplacation
cross-multiplying
The result of multiplying 5 by 3 is 15.
The result of multiplying 27.5 by 3 is 82.5.
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 %
The result of multiplying 27 by 1/3 is 9.
The result of multiplying 28 by 1/3 is 9.
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.
-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)
