Same amount, fewer parts

Step-by-step solution

The problem

\frac{8}{40}

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

    \text{GCF}(8, 40) = 8

  2. Divide the top and bottom by 8. Dividing both by the same number keeps the value the same.

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

All the working together

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