1. multiplicative inverse of -13 = -1/13
2. multiplicative inverse of -13/19 = -19/13
3. -1 × -2/5 = 2/5 . so, multiplicative inverse of 2/5 = 5/2
4. multiplicative inverse of -1 = -1/1 = -1

hope it may help u pls pls pls follow me & mark brainliest ^_^

Answer 2

${\huge{\sf\fcolorbox{blue}{lightpink}{\purple{answer}}}}$

$(i) - 13 = \frac{ - 1}{13 }$

$(ii) \frac{ - 13}{19} = \frac{ - 19}{13 }$

$(v) { - 1} \times \frac{ - 2}{5} = \frac{2}{5} = \frac{5}{2}$

$(vi) - 1 = \frac{ - 1}{1}$
