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."

Find the reciprocal 2 7?
Ah, what a happy little math question we have here! To find the reciprocal of a number, you simply flip it upside down. So, the reciprocal of 2 is 1/2 and the reciprocal of 7 is 1/7. Remember, there are no mistakes in math, just happy little accidents!
Why is it useful to know what a reciprocal is in math?
A reciprocal is useful to know in math because to divide fractions, you must multiply by the second fraction's reciprocal. For example: 2/3 divided by 4/7 is the same as 2/3 times 7/4.
What does the math term 'flip' mean?
Either it is an expression yelled by a teacher when something goes wrong, or it is an alternative term for "to find the reciprocal of". For example, the reciprocal of 3/4 is equal to 4/3 - you have "flipped" the fraction around.
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
What does reciprocal mean in mathmatical terms?
