Write the multiplicative inverse of :

(i) $\dfrac{5}{6}$

(ii) $\dfrac{-3}{7}$

(iii) -8

(iv) $\dfrac{-11}{3}$

(v) $\dfrac{-1}{8}$

(i) $\dfrac{5}{6}$

Since, $\dfrac{5}{6}$ x $\dfrac{6}{5}$ = 1

∴ The multiplicative inverse of $\dfrac{5}{6}$ is $\dfrac{6}{5}$.

(ii) $\dfrac{-3}{7}$

Since, $\dfrac{-3}{7}$ x $\dfrac{-7}{3}$ = 1

∴ The multiplicative inverse of $\dfrac{-3}{7}$ is $\dfrac{-7}{3}$.

(iii) -8

Express -8 as $\dfrac{-8}{1}$

Since, $\dfrac{-8}{1}$ x $\dfrac{-1}{8}$ = 1

∴ The multiplicative inverse of $\dfrac{-8}{1}$ is $\dfrac{-1}{8}$.

(iv) $\dfrac{-11}{3}$

Since, $\dfrac{-11}{3}$ x $\dfrac{-3}{11}$ = 1

∴ The multiplicative inverse of $\dfrac{-11}{3}$ is $\dfrac{-3}{11}$.

(v) $\dfrac{-1}{8}$

Since, $\dfrac{-1}{8}$ x $\dfrac{-8}{1}$ = 1

∴ The multiplicative inverse of $\dfrac{-1}{8}$ is -8.
