2 9 324. Решите уравнение: а) m = -7,2 5,3. ; б) 3,6' 1 4 -7 = 3 x 3 3

• а) Решаем уравнение: \(\frac{m}{-7.2} = \frac{5.3}{3.6}\)

\[m = \frac{-7.2 \cdot 5.3}{3.6} = -2 \cdot 5.3 = -10.6\]

• б) Решаем уравнение: \(\frac{-7\frac{1}{4}}{x} = \frac{9\frac{2}{3}}{3\frac{1}{3}}\)

\[\frac{-\frac{29}{4}}{x} = \frac{\frac{29}{3}}{\frac{10}{3}}\] \[\frac{-\frac{29}{4}}{x} = \frac{29}{3} \cdot \frac{3}{10}\] \[\frac{-\frac{29}{4}}{x} = \frac{29}{10}\] \[x = \frac{-\frac{29}{4}}{\frac{29}{10}} = -\frac{29}{4} \cdot \frac{10}{29} = -\frac{10}{4} = -\frac{5}{2} = -2.5\]
