$\frac{ 2 }{ 3 } \times \frac{ 5 }{ 1 }$
To multiply the fractions, multiply the numerators and denominators separately$\frac{ 2 \times 5 }{ 3 \times 1 }$
Multiply the numbers$\frac{ 10 }{ 3 \times 1 }$
Any expression multiplied by $1$ remains the same$\begin{align*}&\frac{ 10 }{ 3 } \\&\begin{array} { l }3 \frac{ 1 }{ 3 },& 3.\overset{ \cdot }{ 3 } \end{array}\end{align*}$
