9/271/3

Same amount, fewer parts

Step-by-step solution

The problem

\frac{9}{27}

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

    \text{GCF}(9, 27) = 9

  2. Divide the top and bottom by 9. Dividing both by the same number keeps the value the same.

    = \frac{9 \div 9}{27 \div 9} = \textcolor{#0b5c56}{\frac{1}{3}}

All the working together

\begin{aligned} &\frac{9}{27} \\[8pt] &= \frac{9 \div 9}{27 \div 9} && \textcolor{#5b6660}{\textsf{divide by 9}} \\[8pt] &= \textcolor{#0b5c56}{\frac{1}{3}}\end{aligned}
