Step 2. Write the fraction.

A fraction is in simplest form when the numerator and denominator cannot be any smaller, while still being whole numbers.

Fraction of customers who like cookie flavor will be given by-

 $\frac{54}{180}$

Step 3. Write factors of numerator and denominator.

$$\begin{gathered} 54=2\times 3\times 3\times 3 \\ 180=2\times 2\times 3\times 3\times 5 \end{gathered}$$

Step 4. Simplify the fraction.

The fraction $\frac{54}{180}$ can be simplified as in below.

 $$\begin{gathered} \frac{54}{180}=\frac{2\times 3\times 3\times 3}{2\times 2\times 3\times 3\times 5} \\ =\frac{3}{2\times 5} \\ =\frac{3}{10} \end{gathered}$$
