-3.4 (4 is repeating), -3.42 (2 is repeating), 1/3 to the -2 power, -3 and 2/5, in order greatest to least.
\(-3.4444444...\), \(-3.42222222...\), \(({\frac{1}{3}})^{-2}\), \(\frac{2}{5}\) In order from greatest to least.
\(({\frac{1}{3}})^{-2}\)
\(\frac{1}{({\frac{1}{3})}^{2}}\)
\(\frac{1}{\frac{1}{9}}\)
\(\frac{\frac{9}{1}}{1}\)
\(\frac{9}{1}\)
\(9\)
