WebFor example, $8*11$ is $13$, because the product of $8$ and $11$ is $88$, and the remainder of the Euclidean division of $88$ by $15$ is $13$ [the quotient of the division is $5$, and $13=88-(15\times5)$ ]. And the inverse of $7$ is $13$, because similarly $7*13=1$. $\endgroup$ – Web15 Notes. 16 Citations. 17 References.

WebA multiplicative inverse or reciprocal for a number n, denoted by 1 n or n −1 (n to the power of minus one), is a number which when multiplied by n, their product is 1. In other words, the reciprocal of any number is one divided by that number. The reciprocal of a fraction x y is y x. To find the multiplicative inverse of a real number, just ... Web17 aug. 2024 · Step 1: Exchange the numerator and denominator along with their sign i.e. ‘a’ is changed by ‘b’ and ‘b’ is changed by ‘a’. So the multiplicative inverse is ‘b/a’. Step 2: For multiplicative inverse of a number ‘a’, divide 1 by that number along with their sign. The multiplicative inverse of ‘a’ = 1/a. gun shops chester
