Question

18.25-(17-x)=6 5/6
Кто может напишите

Answer 1

Пошаговое объяснение:

$18.25 - (17 - x) = 6 \frac{5}{6} \\ 18.25 - 17 + x = 6 \frac{5}{6} \\ 1.25 + x = 6 \frac{5}{6} \\ x = 6 \frac{5}{6} - 1.25 \\ x = 6 \frac{5}{6} - 1 \frac{25}{100} \\ x = 6 \frac{5}{6} - 1 \frac{1}{4} \\ x = \frac{41}{6} - \frac{5}{4} \\ x = \frac{82}{12} - \frac{15}{12} \\ \times = \frac{67}{12}$

Answer 2

$\displaystyle \tt 18,25-(17-x)=6\frac{5}{6}\\\\ \displaystyle \tt 18,25-17+x=\frac{41}{6}\\\\ \displaystyle \tt 1,25+x=\frac{41}{6}\\\\ \displaystyle \tt x=\frac{41}{6}-1,25\\\\ \displaystyle \tt x=\frac{41}{6}-\frac{5}{4}\\\\ \displaystyle \tt x=\frac{82}{12}-\frac{15}{12}\\\\ \displaystyle \tt x=\frac{67}{12}\\\\\displaystyle \tt \bold{x=5\frac{7}{12}}$
