Same amount, fewer parts

Step-by-step solution

The problem

\frac{27}{33}

  1. Find the greatest common factor. List the factors of each:
    Factors of 27: 1, 3, 9, 27
    Factors of 33: 1, 3, 11, 33
    The greatest common factor (GCF) is 3.

    \text{GCF}(27, 33) = 3

  2. Divide the top and bottom by 3. Dividing both by the same number keeps the value the same.

    = \frac{27 \div 3}{33 \div 3} = \textcolor{#0b5c56}{\frac{9}{11}}

All the working together

\begin{aligned} &\frac{27}{33} \\[8pt] &= \frac{27 \div 3}{33 \div 3} && \textcolor{#5b6660}{\textsf{divide by 3}} \\[8pt] &= \textcolor{#0b5c56}{\frac{9}{11}}\end{aligned}
