How to find reciprocal of a mixed number?
Unlike reciprocal of fractions or whole number, reciprocal of a mixed number requires an additional step to convert the mixed number as an irregular fraction. The inverse of this irregular fraction is a reciprocal of mixed number. For example, 1 1/2 should be converted to its equivalent irregular fraction, so 1 1/2 becomes 3/2. The inverse of 3/2 is a reciprocal of 1 1/2, therefore 2/3 is a reciprocal of 1 1/2.

How to find the reciprocal of a negative number?
