For a number to have a reciprocal, it must be expressible in SIMPLE FRACTIONAL FORM.   So if the number is

TOP/BOTTOM, the reciprocal will be BOTTON/TOP.

So we have to combine the terms of the addition, which is done by simple sixth grade proceduresof adding improper fractions.   So 1-1/2 is 6/4 and 2-3/4 is 11/4.  Take it from there....................
