Answer 1

\(\frac{120}{40}=\frac{30}{10}=3\%\)

Answer 2

\(\frac{120}{40}=\frac{3}{1}=3\)

\(\frac{2.25}{3.05}=\frac{0.45}{0.61}=0.737705\)

\(\frac{135}{183}=\frac{45}{61}=0.737705\)

\(\frac{0.24}{1.3}=0.184615\)

Answer 3

\(\frac{120}{40}=3=300\%\)

\(\frac{2,25}{3,05}=0,7377=73,77\%\)

\(\frac{135}{183}=0,7377=73,77\%\)

\(\frac{0,24}{1,3}=0,1846=18,46\%\)
