What is the term for the multiplicative inverse of a number or fraction?

The term for the multiplicative inverse of a number or fraction is known as the reciprocal. When you take a number and multiply it by its reciprocal, the result is always one. For example, the reciprocal of 2 is 1/2, because 2 multiplied by 1/2 equals 1. Similarly, if you have a fraction, such as 3/4, its reciprocal is 4/3. This concept is fundamental in mathematics, especially in operations involving fractions and solving equations. Understanding reciprocals is essential when dealing with division and multiplicative operations, highlighting their significance in both basic arithmetic and more advanced mathematical contexts.
