Same amount, fewer parts

Step-by-step solution

The problem

\frac{2}{4}

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

    \text{GCF}(2, 4) = 2

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

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

All the working together

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