Question

find the sum of multiplicative inverse of $\frac{-9}{13}$ and additive inverse of 5 upto 6

Answer 1

Multiplicative inverse of -9/13=-13/9.
Additive inverse of 5/6=-5/6
Required sum:
-5/6-13/9
=-(5/6+13/9)
=-((15+28)/18)
=-(43/18)
=-43/18
Ans:The required sum is -43/18.

Answer 2

M.I of $\frac{-9}{13}$ = $\frac{-13}{9}$
A.I of $\frac{5}{6}$ = $\frac{-5}{6}$

According to question :-

$\frac{-13}{9}$ + ($\frac{-5}{6}$
-13/9-5/6
