Answer:
Hence the simplification of
is

Explanation:
" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),
for example: Simplification of a fraction to an irreducible fraction ".
Here we are given a fraction as:

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.
As 66=3×22 and 81=3×27
Hence

Hence the simplification of
is
