Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{2\times 3}{5\times 10}-\frac{2}{5}\times 1\times 5\]
Simplify \(2\times 3\) to \(6\).
\[-\frac{6}{5\times 10}-\frac{2}{5}\times 1\times 5\]
Simplify \(5\times 10\) to \(50\).
\[-\frac{6}{50}-\frac{2}{5}\times 1\times 5\]
Simplify \(\frac{6}{50}\) to \(\frac{3}{25}\).
\[-\frac{3}{25}-\frac{2}{5}\times 1\times 5\]
Cancel \(5\).
\[-\frac{3}{25}-2\]
Simplify.
\[-\frac{53}{25}\]
Decimal Form: -2.12
