A reciprocal is 1 divided by a number.

So, the reciprocal of x is 1/x.

For example:

The reciprocal of 2 is 1/2 is 0.5

The reciprocal of 9 is 1/9 is 0.111111111111

The reciprocal of 0.5 is 1/0.5 is 2.

To divide one by a number is called 'taking the reciprocal.'

If you have a fraction, taking the reciprocal is fairly easy: simply 'flip' it. I.e., put the numerator in the denominator, and the denominator in the numerator.

For example:

The reciprocal of 2/3 is 3/2

The reciprocal of 7/8 is 8/7

The reciprocal of 1/4 is 4 (/1).

The technical mathematical definition of the reciprocal of x is: "The number which, when multiplied by x, gives one."

What does reciprocal math term mean?

The reciprocal of any non-zero number is one divided by that number. The reciprocal of 0 is not defined. For example, if R(x) represents the reciprocal of x, then R(6) = 1/6 R(5/7) = 1 / (5/7) = 1*(7/5) = 7/5 R(x) = 1/x
