Question

Уравнение 5 5/12+(1,375-x)=6 1/6

Answer 1

Ответ:

$5\frac{5}{12} +(1,375-x)=6\frac{1}{6} \\\frac{65}{12} +1,375-x=\frac{37}{6} \\\frac{65}{12} -\frac{37}{6} +1,375-x=0\\\frac{65-74}{12} +1,375-x=0\\-\frac{9}{12} -x+1,375=0\\\frac{-9}{12} +\frac{1375}{1000} -x=0\\\frac{-9000+16500}{12000} -x=0\\\frac{7500}{12000} =x\\x=\frac{75}{120} =\frac{25}{40} =\frac{5}{8} \\x=\frac{5}{8}$
