  • Percent: 25%

1 of 4 equal parts

Step-by-step solution

The problem

\frac{1}{8} + \frac{1}{8}

  1. Add the numerators. Keep the denominator 8.

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

  2. Simplify. List the factors of each:
    Factors of 2: 1, 2
    Factors of 8: 1, 2, 4, 8
    The greatest common factor (GCF) is 2. Divide the top and bottom by 2.

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

All the working together

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