Question

What is the opposite and reciprocal of -7/2?

Answer 1

The opposite and reciprocal of `-7/2` is `2/7`.

Explanation:

With a number x, the reciprocal is known as `1/x`.
So we have our x = `-7/2`, our reciprocal `1/x` `=>` `1/(-7/2)` `=>` `-2/7`.
Since it had asked to be opposite, we put a negative sign in front:
`-(-2/7)` `=>` `2/7`.
Since it had asked for the opposite and reciprocal of `-7/2`, we are done, `2/7`.
