1. ## reciprocal opposites

If two nonzero numbers are opposites of each other, are their reciprocals opposites of each other? Why or why not?

Let n be a number. Its opposite is -n. Let m=-n.

Is the reciprocal of n opposite of the reciprocal of m ? That is to say is 1/n=-1/m ?

Substitute m

Two numbers that have the same absolute value but have opposite signs are called opposite numbers.

If n is one number, then -n is its opposite.

The reciprocal of a fraction is obtained by interchanging the numerator and the denominator, i.e. by inverting the fraction. The reciprocal of a whole number is 1 over that number.

If $\frac{1}{n}$ is one number, then - $\frac{1}{n}$ is its opposite.

If $\frac{m}{n}$ is one number, then - $\frac{m}{n}$ is its opposite.

If $\frac{n}{m}$ is one number, then - $\frac{n}{m}$ is its opposite.

So, the answer is yes. Opposite numbers are the same distance from zero on the number line - one in the negative direction and one in the positive direction.
