Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{3\times 4}{2\times 5}+\frac{9}{5}\times \frac{-10}{3}-(\frac{1}{2}\times \frac{3}{4})\times 45-1873e\]
Simplify \(3\times 4\) to \(12\).
\[-\frac{12}{2\times 5}+\frac{9}{5}\times \frac{-10}{3}-(\frac{1}{2}\times \frac{3}{4})\times 45-1873e\]
Simplify \(2\times 5\) to \(10\).
\[-\frac{12}{10}+\frac{9}{5}\times \frac{-10}{3}-(\frac{1}{2}\times \frac{3}{4})\times 45-1873e\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{12}{10}+\frac{9}{5}\times \frac{-10}{3}-\frac{1\times 3}{2\times 4}\times 45-1873e\]
Simplify \(1\times 3\) to \(3\).
\[-\frac{12}{10}+\frac{9}{5}\times \frac{-10}{3}-\frac{3}{2\times 4}\times 45-1873e\]
Simplify \(2\times 4\) to \(8\).
\[-\frac{12}{10}+\frac{9}{5}\times \frac{-10}{3}-\frac{3}{8}\times 45-1873e\]
Simplify \(\frac{12}{10}\) to \(\frac{6}{5}\).
\[-\frac{6}{5}+\frac{9}{5}\times \frac{-10}{3}-\frac{3}{8}\times 45-1873e\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{6}{5}+\frac{9\times -10}{5\times 3}-\frac{3}{8}\times 45-1873e\]
Simplify \(9\times -10\) to \(-90\).
\[-\frac{6}{5}+\frac{-90}{5\times 3}-\frac{3}{8}\times 45-1873e\]
Simplify \(5\times 3\) to \(15\).
\[-\frac{6}{5}+\frac{-90}{15}-\frac{3}{8}\times 45-1873e\]
Move the negative sign to the left.
\[-\frac{6}{5}-\frac{90}{15}-\frac{3}{8}\times 45-1873e\]
Simplify \(\frac{90}{15}\) to \(6\).
\[-\frac{6}{5}-6-\frac{3}{8}\times 45-1873e\]
Use this rule: \(\frac{a}{b} \times c=\frac{ac}{b}\).
\[-\frac{6}{5}-6-\frac{3\times 45}{8}-1873e\]
Simplify \(3\times 45\) to \(135\).
\[-\frac{6}{5}-6-\frac{135}{8}-1873e\]
Simplify.
\[\frac{-963}{40}-1873e\]
Move the negative sign to the left.
\[-\frac{963}{40}-1873e\]
Decimal Form: -5115.416865
