Question

Решите уравнение дробей с действиями

1) 1/6 = x/36
2) 3/14 =12/x
3) 5/x = 55/66

Answer 1

$1)\frac{1}{6}=\frac{x}{36}\\\\6*x=1*36\\\\6x=36\\\\x=36:6\\\\x=6\\\\Otvet:\boxed{6}\\\\2)\frac{3}{14}=\frac{12}{x}\\\\3*x=14*12\\\\3x=168\\\\x=168:3\\\\x=56\\\\Otvet:\boxed{56}$

$3)\frac{5}{x}=\frac{55}{66}\\\\\frac{5}{x} =\frac{5}{6} \\\\5*x=5*6\\\\x=6\\\\Otvet:\boxed{6}$
