Every non-zero number has a reciprocal, and 0 does not. #### Example -The reciprocal of 3 is 13 +The reciprocal of 3 is 13. -A **reciprocal** can also be defined as a number taken to the power of -1. +You can also get the reciprocal of a fraction by flipping the fraction, or equivalently, the reciprocal of a number can be defined as that number taken to the power of -1. #### Example -13 is same as 8 to the power of -1. - -You can also take a reciprocal of a fraction by flipping the fraction. -For instance, reciprocal of 23 is 32. +The reciprocal of 23 is 32 since 1/(23) = 3/2, or (23)-1 = 3/2. ### Note -1. Reciprocal of a reciprocal is the original number. +1. The reciprocal of the reciprocal of a number is the original number. #### Example -Reciprocal of 23 is 123. Now if we take the reciprocal of 123 and filp the fraction, we get 231 which is the original number. +The reciprocal of 23 is 123. Now if we look at the reciprocal of 123 we get 231, which is the original number. -2. If you multiply a number by its reciprocal, you always get 1. +2. If you multiply a non-zero number by its reciprocal, you always get 1. #### Example -Reciprocal of 16 is 116. If you multiply 116 with 16, you get 1. - -3. Zero does not have a reciprocal - - -#### More Information: - - - +The reciprocal of 16 is 116. If you multiply 116 by 16, you get 1.
