Question 1 Report

The binary operation $\oplus$ defined on the set of real numbers is such that x $\oplus$ y = $\frac{x y}{6}$ for all x, y $ϵ$ R. Find the inverse of 20 under this operation when the identity element is 6

\frac{9}{5}

\frac{1}{20}

\frac{10}{3}

\frac{1}{12}

Answer Details

$\frac{\frac{1}{20} \times 6}{6}$ = $\frac{6}{20}$ x $\frac{1}{6}$ = $\frac{1}{20}$
