so sánh

A=\(\frac{3}{83}+\frac{7}{84}\)

B=\(\frac{7}{83}+\frac{3}{84}\)

Answer 1

\(A=\frac{3}{83}+\frac{7}{84}=\frac{252}{6972}+\frac{581}{6972}=\frac{833}{6972}=\frac{119}{996}\)

\(B=\frac{7}{83}+\frac{3}{84}=\frac{588}{6972}+\frac{249}{6972}=\frac{837}{6972}=\frac{279}{2324}\)

\(\Rightarrow A< B\)
