Steps to Solve

Identify the GCD of the numbers
Since 27 and 20 have no common divisors other than 1, we determine their GCD.
The prime factorization shows:
 27 is $3^3$
 20 is $2^2 \times 5$
Both numbers share no common prime factors. Thus, the GCD is 1.

Simplifying the fraction
When simplifying a fraction, divide both the numerator and the denominator by their GCD.
Since the GCD is 1:
$$ \frac{27 \div 1}{20 \div 1} = \frac{27}{20} $$
The fraction remains $\frac{27}{20}$. 
Conclusion about the fraction
The fraction $\frac{27}{20}$ is already in its simplest form, as further simplification isn't possible.
The simplified fraction is ( \frac{27}{20} ).
More Information
This fraction, ( \frac{27}{20} ), can also be expressed as a mixed number. Dividing gives ( 27 \div 20 = 1 ) with a remainder of 7, yielding ( 1 \frac{7}{20} ).
Tips
 Assuming there is a common factor without checking: Always perform the GCD calculation to confirm.
 Forgetting to divide both the numerator and denominator by the GCD: This results in an incorrect simplification.
