Question

Реши уравнение:(5/9x-1/4)•1/6=1/16

Answer 1

Ответ:

1.125

Пошаговое объяснение:

$(\frac{5}{9}x-\frac{1}{4})*\frac{1}{6}=\frac{1}{16}\\\\ \frac{5}{9}x-\frac{1}{4}=\frac{1}{16}:\frac{1}{6}\\\\ \frac{5}{9}x-\frac{1}{4}=\frac{1}{16}*6\\\\\frac{5}{9}x-\frac{1}{4}=\frac{3}{8}\\\\\frac{5}{9}x=\frac{3}{8}+\frac{1}{4}\\\\ \frac{5}{9}x=\frac{3}{8}+\frac{2}{8}\\\\\frac{5}{9}x=\frac{5}{8}\\\\ x=\frac{5}{8}:\frac{5}{9}\\\\ x=\frac{5}{8}*\frac{9}{5}\\\\ x=\frac{9}{8}\\\\ x=1.125$
