\(A=\frac{111111}{121212}+\frac{111111}{202020}+\frac{111111}{303030}\)
A = \(\frac{2-\frac{2}{19}}{3-\frac{3}{19}}+\frac{\frac{2}{43}-\frac{2}{1943}}{\frac{3}{43}-\frac{3}{1943}}:\frac{4-\frac{4}{29}+\frac{4}{41}-\frac{4}{2941}}{5-\frac{5}{29}+\frac{5}{41}-\frac{5}{2941}}\)
tính nhanh:
A=\(\frac{\frac{3}{7}-\frac{3}{17}+\frac{3}{37}}{\frac{5}{7}-\frac{5}{17}+\frac{5}{37}}+\frac{\frac{1}{2}-\frac{1}{3}+\frac{1}{4}-\frac{1}{5}}{\frac{7}{5}-\frac{7}{4}+\frac{7}{3}-\frac{7}{2}}\)
giải chi tiết nhé các bạn
\(B=\frac{4+\frac{4}{5}+\frac{4}{155}-\frac{4}{1555}+\frac{4}{235}}{8+\frac{8}{5}+\frac{16}{310}+\frac{8}{235}-\frac{8}{1555}}.\frac{1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}}{4+\frac{3}{2}+\frac{3}{4}}\)
\(M=\frac{\frac{3}{5}+\frac{3}{7}-\frac{3}{11}}{\frac{4}{5}+\frac{4}{7}-\frac{4}{11}}\)
A=\(\frac{3.7.13.37.39-10101}{505050+70707}\)
\(\left(19-\frac{5}{8}:\frac{7}{12}-13\frac{1}{4}:\frac{7}{12}\right).\frac{4}{5}\)
\(P=\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
tính bằng cách thuận tiện :
a)\(\frac{37}{25}:\frac{5}{4}:\frac{74}{25}\)
\(\frac{6}{11}:\frac{4}{3}:\frac{5}{11}:\frac{4}{3}\)
