Answer:
Hence the simplification of 
is 
Step-by-step explanation:
<em>" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), </em>
<em>for example</em><em>: Simplification of a fraction to an irreducible fraction ". </em>
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
-A rectangle<span> is a four-sided shape each angle is a </span>right angle<span>.
</span>
-A rhombus is a four-sided figure and all sides have equal length. Opposite sides are parallel and opposite angles are equal.
-A square has equal sides and every angle is a right angle. Opposite sides are parallel.
-A parallelogram<span> has opposite sides parallel and the sides lengths are the same. Opposite angles are equal </span>
Honestly photo math is the way to go but I got r= 17/13
