Example Question #1 : How To Find The Reciprocal Of A Fraction
What is the slope of any line perpendicular to 4y = 2x + 7 ?
First, we must solve the equation for y to determine the slope: y = (2/4)x + 7/4
By looking at the coefficient in front of x, we know that the slope of this line has a value of 1/2. To find the slope of any line perpendicular to this one, we take the negative reciprocal of it:
slope = m , perpendicular slope = –1/m
slope = 1/2 , perpendicular slope = –2
Example Question #1 : How To Find The Reciprocal Of A Fraction
Find the reciprocal of the following fraction
The reciprocal is defined such that a faction times its recprocal is 1. For you this just means turn the fraction upside down, ie the numerator is the denominator and vice versa.

What is the reciprocal of ?
This fraction doesn't have a reciprocal.
The reciprocal of a fraction is simply exchanging the denominator and numerator of a fraction.
You can double check that it works by making sure the product of a fraction and its reciprocal is 1.
