\(A=\frac{0,375-0,3+\frac{3}{10}+\frac{3}{12}}{-0,625+0,5-\frac{5}{11}-\frac{5}{12}}+\frac{1,5+1-0,75}{2,5+\frac{5}{3}-1,25}\)
\(\Rightarrow A=\frac{\frac{3}{8}-\frac{3}{10}+\frac{3}{11}+\frac{3}{12}}{\frac{-5}{8}+\frac{5}{10}-\frac{5}{11}-\frac{5}{12}}+\frac{\frac{3}{2}+\frac{3}{3}-\frac{3}{4}}{\frac{5}{2}+\frac{5}{3}-\frac{5}{4}}\)
\(\Rightarrow A=\frac{-3.\left(-\frac{1}{8}+\frac{1}{10}-\frac{1}{11}-\frac{1}{12}\right)}{5\left(-\frac{1}{8}+\frac{1}{10}-\frac{1}{11}-\frac{1}{12}\right)}+\frac{3.\left(\frac{1}{2}+\frac{1}{3}-\frac{1}{4}\right)}{5\left(\frac{1}{2}+\frac{1}{3}-\frac{1}{4}\right)}\)
\(\Rightarrow A=\frac{-3}{5}+\frac{3}{5}\)
\(\Rightarrow A=0\)
Vậy A = 0
