Solution

Given, `-2 1/9 - 6`

If verbs in chinchle join the verb:

`(- 19)/9 - 6`

Now LCM of the denominator of the latter parameter = 9 × 1 = 9

= `(- 19 - (6 xx 9))/9`

= `(- 19 - 54)/9`

= `(- 73)/9`

The numerator and denominator of the obtained rational number have no other multiple than 1

Hence, `(- 73)/9`
