Solution


Move the negative sign to the left.
\[\frac{{247}^{2}}{{225}^{2}}\times -3\]
Simplify  \({247}^{2}\)  to  \(61009\).
\[\frac{61009}{{225}^{2}}\times -3\]
Simplify  \({225}^{2}\)  to  \(50625\).
\[\frac{61009}{50625}\times -3\]
Use this rule: \(\frac{a}{b} \times c=\frac{ac}{b}\).
\[\frac{61009\times -3}{50625}\]
Simplify  \(61009\times -3\)  to  \(-183027\).
\[\frac{-183027}{50625}\]
Move the negative sign to the left.
\[-\frac{183027}{50625}\]
Simplify  \(\frac{183027}{50625}\)  to  \(\frac{61009}{16875}\).
\[-\frac{61009}{16875}\]
