\(\left(\frac{1}{4}\times y-\frac{1}{8}\right)\times\frac{3}{4}=\frac{1}{8}\)
\(\frac{1}{4}\times y-\frac{1}{8}=\frac{1}{8}:\frac{3}{4}\)
\(\frac{1}{4}\times y-\frac{1}{8}=\frac{1}{6}\)
\(\frac{1}{4}\times y=\frac{1}{6}+\frac{1}{8}\)
\(\frac{1}{4}\times y=\frac{7}{24}\)
\(y=\frac{7}{24}:\frac{1}{4}\)
\(y=\frac{7}{6}\)
