Find the multiplicative inverse of 1/2-2/3+5/4

Answers (1)

To find the multiplicative inverse, we have to find out the LCM first

\begin{aligned} & \frac{1}{2}=\frac{6}{12} \\ & \frac{2}{3}=\frac{8}{12} \\ & \frac{5}{4}=\frac{15}{12} \end{aligned}

\frac{6}{12}-\frac{8}{12}+\frac{15}{12}=\frac{(6-8+15)}{12}=\frac{13}{12}

Now the multiplicative inverse will be, 

\frac{12}{13}
