Find the multiplicative inverse of the following. (i) `- 13 ` (ii) `(-13)/(19)` (iii) `1/5` (iv) `(- 5)/8 xx (-3)/7` (v) `- 1 xx (-2)/5` (vi) `- 1`

Explanation

To find the multiplicative inverse of a number \( x \), we need to find a number \( y \) such that \( x \times y = 1 \). The multiplicative inverse is also known as the reciprocal of the number.

Let's solve the given problems step by step:

### (i) Find the multiplicative inverse of \(-13\)

1. Let the multiplicative inverse of \(-13\) be \( x \).
2. According to the definition, we have:
