Multiplicative inverse explained In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x-1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function f (x ... Multiplicative inverse Here you will learn about the multiplicative inverse , including the definition and how to find it. Students will first learn about the multiplicative inverse in 6 th grade math as part of their work in number and operations with fractions when they learn how to divide fractions and extend their knowledge as they work through number systems in middle school. Multiplicative Inverse Some mathematical calculations can be complex while solving them. The multiplicative inverse is a technique in mathematics that simplifies complex mathematical problems to solve them easily. As the term denotes, multiplicative inverse means applying multiplication operation inversely or in reverse. Therefore, we do not need to perform any extra multiplication operation in multiplicative inverse . Definition Multiplicative inverse means getting such a number which, when ...
