Best Answer

A reciprocal is useful to know in math because to divide fractions, you must multiply by the second fraction's reciprocal. For example:

2/3 divided by 4/7

is the same as

2/3 times 7/4.

What is the definition of a negative reciprocal?

Negative reciprocal is something you use in math that often times help you find a perpendicular line to an equation. ex: for an equation with a slope of 5x, the recriprocal would be -1/5x. what you do is you flip flop the bottom and the top, 1/5x. That is the reciprocal alone and to make it a negative reciprocal you just simply add the negative sign.
