Реши уравнение: 5 3/4:4 1/8=b:3,3.

\[5\frac{3}{4}\ :4\frac{1}{8} = b\ :3,3\]

\[\frac{23}{4}\ :\frac{33}{8} = b\ :\frac{33}{10}\]

\[\frac{23}{4} \cdot \frac{8}{33} = b \cdot \frac{10}{33}\]

\[b \cdot \frac{10}{33} = \frac{46}{33}\]

\[b = \frac{46}{33} \cdot \frac{33}{10}\]

\[b = \frac{46}{10}\]

\[b = 4,6.\ \]
