ГДЗ по математике 5 класс Мерзляк ФГОС Задание 948

 

\[\boxed{\ \mathbf{948\ (948)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ p = 0,14:\]

\[0,13p + 0,47p = 0,60p =\]

\[= 0,6 \cdot 0,14 = 0,084.\]

\[2)\ b = 5,4:\]

\[0,72b - 0,043b = 0,029b =\]

\[= 0,029 \cdot 5,4 = 0,1566.\]

\[3)\ x = 0,678:\]

\[3,8x + 1,7x - 5,4x + 0,1x =\]

\[= 5,5x - 5,3x = 0,2x =\]

\[= 0,2 \cdot 0,678 = 0,1356.\]

\[4)\ c = 0,58:\]

\[8,6c - 3,5c - 0,1c + 0,296 =\]

\[= 5c + 0,296 =\]

\[= 5 \cdot 0,58 + 0,296 =\]

\[= 2,9 + 0,296 = 3,196.\]

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

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

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

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

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

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

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

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

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