6/181/3

Same amount, fewer parts

Step-by-step solution

The problem

\frac{6}{18}

  1. Find the greatest common factor. List the factors of each:
    Factors of 6: 1, 2, 3, 6
    Factors of 18: 1, 2, 3, 6, 9, 18
    The greatest common factor (GCF) is 6.

    \text{GCF}(6, 18) = 6

  2. Divide the top and bottom by 6. Dividing both by the same number keeps the value the same.

    = \frac{6 \div 6}{18 \div 6} = \textcolor{#0b5c56}{\frac{1}{3}}

All the working together

\begin{aligned} &\frac{6}{18} \\[8pt] &= \frac{6 \div 6}{18 \div 6} && \textcolor{#5b6660}{\textsf{divide by 6}} \\[8pt] &= \textcolor{#0b5c56}{\frac{1}{3}}\end{aligned}
