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

Answer:
$2.41
Step-by-step explanation:
There are 4 quarts in a gallon. If there are 3 gallons that means there is 12 quarts (3x4=12) You then take $28.92 and divide it by 12, which will give you 2.40833333 and on and on, you round that to $2.41. I hope that helps!
