\[-\frac{14}{13}\times \frac{52}{28}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{14\times 52}{13\times 28}\]
Simplify \(14\times 52\) to \(728\).
\[-\frac{728}{13\times 28}\]
Simplify \(13\times 28\) to \(364\).
\[-\frac{728}{364}\]
Simplify \(\frac{728}{364}\) to \(2\).
