### Instruction: Simplify the fraction $\frac{27}{30}$.### Response: To simplify a fraction, I need to find the greatest common factor (GCF) of the numerator and the denominator, and then divide both by that factor.
The GCF of 27 and 30 is 3, since 3 is the largest number that divides both 27 and 30 evenly.
So, to simplify the fraction, I divide both 27 and 30 by 3.
I get $\frac{27}{30} = \frac{27 \div 3}{30 \div 3} = \frac{9}{10}$.
