\(=\frac{432x2x48-432x96}{846x48x432}\)
\(=\frac{432x96-432x96}{846x48x432}\)
\(=\frac{0}{846x48x432}\)
\(=0\)
\(\frac{864\cdot48-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{432\cdot2\cdot48-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{432\cdot96-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{96\cdot\left(432-432\right)}{864\cdot48\cdot432}\)
\(=0\)
