Пошаговое объяснение:

а) [tex]\frac{3}{14} x = 1[/tex]

[tex]x = \frac{14}{3}[/tex] = 4[tex]\frac{2}{3}[/tex]

б) [tex]\frac{5}{12}x =\frac{1}{2}[/tex]

[tex]x = \frac{12}{5}*\frac{1}{2}\\x = \frac{12}{10}\\x = \frac{6}{5} \\x = 1\frac{1}{5}[/tex]

в)

[tex]\frac{4}{9}x = 2\frac{2}{3}\\ \frac{4}{9}x = \frac{8}{3}\\ x = \frac{9}{4}* \frac{8}{3}\\ x = 6[/tex]

г)

[tex]1\frac{7}{10}x=6 \frac{4}{5} \\\frac{17}{10}x= \frac{34}{5} \\x = \frac{10}{17} *\frac{34}{5}\\x = 4[/tex]
