$\frac{21}{81}\times\frac{63}{105}$ Simplify each fraction. $\frac{21}{81}=\frac{7}{27}$, $\frac{63}{105}=\frac{3}{5}$ Use cross-simplification to further reduce before multiplying. $\frac{7}{27}\times\frac{3}{5} = \frac{7}{9}\times\frac{1}{5}$ Multiply. $\frac{7}{9}\times\frac{1}{5} = \frac{7}{45}$
