tính nhanh nha
D=\(\frac{3}{2x4}+\frac{3}{4x6}+...+\frac{3}{98x100}\)
A=\(\frac{1}{2}+\frac{1}{3}+\frac{1}{6}+\frac{1}{12}\)
B=\(6\frac{2}{3}+7\frac{5}{8}+3\frac{1}{3}+4\frac{5}{8}\)
C=[\(4\frac{2}{5}+2\frac{3}{7}\)] - [\(2\frac{2}{5}-1\frac{4}{7}\)]

\(1:\frac{1}{2}:\frac{2}{3}:\frac{3}{4}:\frac{4}{5}:\frac{5}{6}:\frac{6}{7}:\frac{7}{8}=........\)
Tính:
a,\(\frac{\left(3+\frac{1}{6}\right)-\frac{2}{5}}{\left(5-\frac{1}{6}\right)+\frac{7}{10}}\)
b,\(\frac{\left(4,08-\frac{2}{25}\right):\frac{4}{17}}{\left(6\frac{5}{9}-3\frac{1}{4}\right)x2\frac{2}{7}}\)
c,\(\frac{2-\frac{1}{4}+\frac{1}{3}-\frac{3}{5}}{3-\frac{1}{5}-\frac{5}{3}}\)
\(\frac{10+\frac{9}{2}+\frac{8}{3}+\frac{7}{4}+ \frac{6}{5}+\frac{5}{6}+\frac{4}{7}+\frac{3}{8}+\frac{2}{9}+\frac{1}{10}}{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{10}+\frac{1}{11}}\)
\(\frac{8}{1}+\frac{7}{2}+\frac{6}{3}+\frac{5}{4}+\frac{4}{5}+\frac{3}{6}+\frac{2}{7}+\frac{1}{8}\)
tính bằng cách thuận tiện nhất: \(6\frac{2}{7}+7\frac{3}{5}+8\frac{6}{9}+9\frac{1}{4}+\frac{2}{5}+\frac{5}{7}+\frac{1}{3}+\frac{3}{4}\)
Tính nhanh:
A=\(\left(\frac{2}{5}+\frac{2}{9}+\frac{2}{11}\div\frac{7}{5}+\frac{7}{9}+\frac{7}{11}\right)\div\left(\frac{1}{3}-\frac{1}{4}+\frac{1}{5}\div\frac{7}{6}-\frac{7}{8}+\frac{7}{10}\right)\)
\(\frac{1}{2}:3+\frac{1}{3}:4+\frac{1}{4}:5+\frac{1}{5}:6+\frac{1}{6}:7+\frac{1}{7}:8....\frac{1}{99}+100\)
