When multiplying fractions, we multiply the numerators and we multiply the denominators:

\[ \dfrac{\orange{\text{numerator}}}{\blue{\text{denominator}}} \times \dfrac{\orange{\text{numerator}}}{\blue{\text{denominator}}} = \dfrac{\orange{\text{numerator}}\times \orange{\text{numerator}}}{\blue{\text{denominator}} \times \blue{\text{denominator}}} \]

Example
\[\begin{array}{rcl}
\dfrac{\orange{5}}{\blue{7}} \times \dfrac{\orange{2}}{\blue{9}} &=&
\dfrac{\orange{5}\times\orange{2}}{\blue{7}\times \blue{9}}\\
&=& \dfrac{10}{63}
\end{array} \]
