Answer 1

$\displaystyle 3\frac{1}{16}:(x-\frac{5}{16})=\frac{7}{8},x\neq \frac{5}{16}\\\\ \frac{49}{16}:\frac{16x-5}{16}=\frac{7}{8}\\\\ \frac{49}{16}*\frac{16}{16x-5}=\frac{7}{8}\\\\ 49*\frac{1}{16x-5}=\frac{7}{8}\\\\ \frac{49}{16x-5}=\frac{7}{8}\\\\ 392=7(16x-5)\\56=16x-5\\-16x=-5-56\\-16x=-61\\\\ x=\frac{61}{16}=3\frac{13}{16}=3,8125$
