never a negative number * * * * * ... true if, by opposite, you mean the additive inverse. However, the multplicative inverse is also an opposite. And the multiplicative inverse of a negative number is always negative.
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
Negative 7 over 4.
It certainly is not. -1 is the opposite of 1 The inverse of a number is 1 divided by that number, or its reciprocal. The inverse of 1 is 1/1 = 1
- 1/3
negative one third.
-3
Flip it upside down. Now you have negative three over four. That's your multiplicative inverse (reciprocal) -3/4
If the multiplicative inverse of a number is the number that you could multiply with the original number in order to obtain one, then the mulitplicative inverse of -15 and 2/3 is -3/47 negative three fourtysevenths, or negative three over fourtyseven.
-2/3 -> [mult.inverse] -> -3/2 which is -1½or -1.5 ; note that a number, when multiplied by its multiplicative inverse will have a product of 1. So if you multiply these two you get 6/6 which equals 1 [negative times negative is positive].
No. The additive inverse of zero or a negative rational number is not negative.
The multiplicative inverse of -3 is -(1/3) or negative one-third. The multiplicative inverse of a number is the number that you multiply it by to get a result of 1 (the multiplicative identity). So, since -3 times -(1/3) is 1, -(1/3) is the multiplicative inverse of -3. Similarly, +3 is the ADDITIVE inverse of -3. The additive inverse of a number is the number you add to it to get a result of 0 (the additive identity). So, since -3 + (+3) = 0, +3 is the additive inverse of -3. The original answer given here was that the multiplicative inverse of -3 is +3, which is flat incorrect.
The multiplicative inverse is the negative of the reciprocal of the positive value. Thus the multiplicative inverse of -7 is -1/7.

Yes
0
A number and its multiplicative inverse have the same sign. So if one is negative, so is the other.
