What is the reciprocal of 6 3/7?
77julia77 [94]
I believe your answer is going to be -6 7/3. Reciprocals are the opposites of a number, so I switched the sign on the 6 and made it -. When dealing with fractions, the reciprocal is essentially just flipping the numerator and denominator, which is how I got 7/3. 

I hope I helped. Best of luck!
