Break Down $27$ : Let's break down $27$ into its prime factors. $\newline$ $27 = 3 \times 9$ $\newline$ But $9$ is not a prime number, so we need to break it down further. $\newline$ $9 = 3 \times 3$ $\newline$ So, $27 = 3 \times 3 \times 3$
Break Down $54$ : Now let's break down $54$ into its prime factors. $\newline$ $54 = 2 \times 27$ $\newline$ And we already know that $27 = 3 \times 3 \times 3$ $\newline$ So, $54 = 2 \times 3 \times 3 \times 3$
Write Fraction in Prime Form: Now we write the fraction in prime factored form. $\frac{27}{54} = \frac{(3 \times 3 \times 3)}{(2 \times 3 \times 3 \times 3)}$
Cancel Common Factors: We can now cancel out the common factors. $\newline$ $(3 \times 3 \times 3)/(2 \times 3 \times 3 \times 3) = 1/2$ after canceling out the $3$ s.
