\(x . 3 . \frac{1}{4}=\frac{11}{4}\)
\(\Rightarrow x.3=\frac{11}{4}:\frac{1}{4}=11\)
\(\Rightarrow x=\frac{11}{3}\)
\(x\)x 3 x \(\frac{1}{4}\)= \(\frac{11}{4}\)
\(x\)x \(\frac{3}{4}=\frac{11}{4}\)
\(x=\frac{11}{4}\): \(\frac{3}{4}\)
\(x=\frac{11}{3}\)
\(x\times3\times\frac{1}{4}=\frac{11}{4}\)
\(x\times3=\frac{11}{4}\div\frac{1}{4}\)
\(x\times3=11\)
\(x=11\div3\)
\(x=\frac{11}{3}\)
\(\frac{1}{2}\)x \(x\)x 3 = \(\frac{5}{2}\)
\(\frac{1}{2}\)x 3 x \(x=\frac{5}{2}\)
\(\frac{3}{2}\times x=\frac{5}{2}\)
\(x=\frac{5}{2}\): \(\frac{3}{2}\)
\(x=\frac{5}{3}\)
\(\frac{1}{2}.x.3=\frac{5}{2}\)
\(\Rightarrow\frac{1}{2}.x=\frac{5}{2}:3=\frac{5}{6}\)
\(\Rightarrow x=\frac{5}{6}:\frac{1}{2}=\frac{5}{3}\)
\(\frac{1}{2}\times x\times3=\frac{5}{2}\)
\(\frac{1}{2}\times x=\frac{5}{2}\div3\)
\(\frac{1}{2}\times x=\frac{5}{6}\)
\(x=\frac{5}{6}\div\frac{1}{2}\)
\(x=\frac{5}{3}\)
