Same amount, fewer parts

Step-by-step solution

The problem

\frac{4}{8}

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

    \text{GCF}(4, 8) = 4

  2. Divide the top and bottom by 4. Dividing both by the same number keeps the value the same.

    = \frac{4 \div 4}{8 \div 4} = \textcolor{#0b5c56}{\frac{1}{2}}

All the working together

\begin{aligned} &\frac{4}{8} \\[8pt] &= \frac{4 \div 4}{8 \div 4} && \textcolor{#5b6660}{\textsf{divide by 4}} \\[8pt] &= \textcolor{#0b5c56}{\frac{1}{2}}\end{aligned}
