\(\frac{7}{8}-\frac{1}{4}=2-....\)
\(\Rightarrow\frac{5}{8}=2-.....\)
\(\Rightarrow2-\frac{5}{8}\)
\(\Rightarrow\frac{11}{8}\)
Vậy \(\frac{7}{8}-\frac{1}{4}=2-\frac{11}{8}\)
\(\frac{7}{8}-\frac{1}{4}=2-\frac{11}{8}\)
\(\frac{7}{8}-\frac{1}{4}=2-...\)
\(=\frac{5}{8}=2-....\)
\(=2-\frac{5}{8}=\frac{11}{8}\)
\(\Rightarrow\frac{7}{8}-\frac{1}{4}=2-\frac{11}{8}\)
