(i) The multiplicative inverse of -13 is \frac{-1}{13} because  -13\times \frac{-1}{13} = 1

(ii) The multiplicative inverse of \frac{-13}{19} is \frac{-19}{13} because of i

(iii) The multiplicative inverse of \frac{1}{5}  is 5 because   \frac{1}{5}\times 5 = 1

(iv) The multiplicative inverse of \frac{-5}{8}\times \frac{-3}{7} is  \frac{56}{15}  because  \frac{15}{56}\times \frac{56}{15} = 1

(v) The multiplicative inverse of -1\times \frac{-2}{5} is  \frac{5}{2} because   \frac{2}{5}\times \frac{5}{2} = 1

(vi) The multiplicative inverse of -1 is -1 because -1\times -1 = 1
