The expression is

\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{2}{12}

To find:

The expression which is equivalent to the given expression.

Solution:

We have,

\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{2}{12}

It can be written as

=\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{1}{6}

Taking LCM, we get

=\dfrac{16-5-1}{6}

=\dfrac{10}{6}

=\dfrac{5}{3}

The mixed fraction of this improper fraction is

=\dfrac{1\times 3+2}{3}

=1\dfrac{2}{3}

So, the expression 1\dfrac{2}{3} is equivalent to the given expression.

Therefore, the correct option is A.
