The concepts for this exercise are summarized below.
For a complete discussion, read the text.
Here, you will practice finding reciprocals (multiplicative inverses) of whole numbers and fractions.
For x ≠ 0 , the reciprocal of x is 1/x .
In particular, the reciprocal of a/b is b/a .
The number 0 does not have a reciprocal.
For all other numbers, a number multiplied by its reciprocal equals 1 .
EXAMPLES:
The reciprocal of 5 is 1/5 .
The reciprocal of 2/3 is 3/2 .
The reciprocal of -6 is -1/6 .
The reciprocal of -5/7 is -7/5 .
The reciprocal of 0 is not defined (input 'nd').
