Solution 1.1:5a
From Förberedande kurs i matematik 1
It is easier to see the mutual order of the numbers if we write them as decimals.
Because we know that \displaystyle {1}/{5}\;=0.2 and \displaystyle {1}/{3}\;=0.333..., we obtain
\displaystyle \begin{align}
& \frac{3}{5}=3\centerdot \frac{3}{5}=3.02=0.6 \\
& \\
& \frac{5}{3}=\frac{3+2}{3}=1+\frac{2}{3}=1.666... \\
& \\
& \frac{7}{3}=\frac{6+1}{3}=2+\frac{1}{3}=2.333... \\
\end{align}
