Question

Select the phrases that mean "opposite of."

reciprocal

negative

additive inverse

multiplicative inverse

minus

absolute value

Answer 1

Strange question.  Sort of needs more context to be good.

I'd go for all of them, except the absolute value.

Even absolute value is opposite if the input is negative, but not in general.

reciprocal - multiplicative inverse  sort of the same

negative x = additive inverse of x = minus x  => sort of the same

Answer 2

the answer is reciprocal

example: 2/3 is the reciprocal of 3/2
