ГДЗ по математике 5 класс Мерзляк ФГОС Задание 948

\[\boxed{\mathbf{948}.\ }\]

\[1)\ \frac{a}{6} = \frac{9}{54}\]

\[\frac{a}{6} = \frac{1}{6} \Longrightarrow a = 1.\]

\[2)\ \frac{7}{a} = \frac{49}{28}\]

\[\frac{7}{a} = \frac{7}{4} \Longrightarrow a = 4.\]

\[3)\ \frac{27}{45} = \frac{3}{a}\]

\[\frac{3}{a} = \frac{3}{5} \Longrightarrow a = 5.\]

\[4)\ \frac{a}{32} = \frac{5}{8}\]

\[\frac{a}{32} = \frac{20}{32} \Longrightarrow a = 20.\]
