Answer 2

Answer: Second option is correct.

Explanation:

Since we have given that

`-18(1)/(4)/ 2(2)/(3)`

We need to find the best estimation:

First we change the mixed fraction into improper fraction:

`-18(1)/(4)\approx -18`

and

`2(2)/(3)=(8)/(3)=2.6666....\approx 3`

So, it becomes,

`-18/3\\\\=(-18)/(3)`

Hence, Second option is correct.
