Same amount, fewer parts

Step-by-step solution

The problem

\frac{5}{40}

  1. Find the greatest common factor. List the factors of each:
    Factors of 5: 1, 5
    Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
    The greatest common factor (GCF) is 5.

    \text{GCF}(5, 40) = 5

  2. Divide the top and bottom by 5. Dividing both by the same number keeps the value the same.

    = \frac{5 \div 5}{40 \div 5} = \textcolor{#0b5c56}{\frac{1}{8}}

All the working together

\begin{aligned} &\frac{5}{40} \\[8pt] &= \frac{5 \div 5}{40 \div 5} && \textcolor{#5b6660}{\textsf{divide by 5}} \\[8pt] &= \textcolor{#0b5c56}{\frac{1}{8}}\end{aligned}
