(i) `- 13 `
(ii) `(-13)/(19)`
(iii) `1/5`
(iv) `(- 5)/8 xx (-3)/7`
(v) `- 1 xx (-2)/5`
(vi) `- 1`

Text Solution

Verified by Experts

Reciprocal of a number is known as its multiplicative inverse.
(i) Multiplicative inverse of -13 is `-frac{1}{13}`

(ii) Multiplicative inverse of `-frac{13}{19}` is `-frac{19}{13}`

(iii) Multiplicative inverse of `frac{1}{5}` is `5`.

(iv) `-frac{5}{8}xx-frac{3}{7}=frac{15}{56}`
