Common Denominator Practice

Instructions: Create equivalent fractions with common denominators for each pair of fractions. On this page, we will find the common denominator by multiplying the denominators of the two fractions.

Example:
[tex]\[

\begin{align*}

\frac{1}{2} \times \frac{10}{10} &= \frac{10}{20} \\

\frac{3}{10} \times \frac{2}{2} &= \frac{6}{20} \\

\frac{2}{3} \times \frac{6}{6} &= \frac{12}{18} \\

\frac{2}{6} \times \frac{3}{3} &= \frac{6}{18} \\

\frac{1}{4} \times \frac{8}{8} &= \frac{8}{32} \\

\frac{1}{8} \times \frac{4}{4} &= \frac{4}{32} \\

\frac{1}{2} \times \frac{3}{3} &= \frac{3}{6} \\

\frac{2}{3} \times \frac{2}{2} &= \frac{4}{6} \\

\frac{3}{8} \times \frac{3}{3} &= \frac{9}{24} \\

\frac{1}{3} \times \frac{8}{8} &= \frac{8}{24}

\end{align*}
