tính nhanh:\(\frac{\left(\frac{1}{2}+0,25+\frac{1}{4}\right)+\left(\frac{1}{8}+\frac{3}{2}+\frac{1}{8}+\frac{25}{100}\right)+\left(0,75+\frac{1}{5}+50\%+\frac{1}{4}+0,55+\frac{45}{100}\right)}{1x2x3}\)
\(\frac{\left(\frac{1}{2}+0,25+\frac{1}{4}\right)+\left(\frac{1}{8}+\frac{3}{2}+\frac{1}{8}+\frac{25}{100}\right)+\left(0,75+\frac{1}{2}+50\%+\frac{1}{4}+0,55+\frac{145}{100}\right)}{1x2x3}\)
Tính : \(\left(92-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-...-\frac{92}{100}\right)\) \(\div\left(\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+...+\frac{1}{500}\right)\)
Tính giá trị biểu thức:
\(A=\frac{\frac{16}{10}:\left(1\frac{3}{5}\times \frac{5}{4}\right)}{\frac{64}{100}-\frac{1}{25}}+\frac{\left(\frac{108}{100}-\frac{2}{25}\right):\frac{4}{7}}{\left(5\frac{5}{9}-2\frac{1}{4}\right)\times 2\frac{2}{17}}+\frac{3}{5}\times \frac{1}{2}:\frac{2}{5}\)
\(\frac{10}{11}x\frac{12}{13}:\frac{50}{51}-\frac{19}{20}x\frac{12}{13}:\frac{101}{102}+\frac{99}{100}\)
Tính: \(S=\frac{92-\frac{1}{9}-\frac{2}{10}-\frac{3}{11}-....-\frac{90}{98}-\frac{91}{99}-\frac{92}{100}}{\frac{1}{45}+\frac{1}{50}+\frac{1}{55}+....+\frac{1}{495}+\frac{1}{500}}\)
Giúp mình nha! ^_^
tính nhanh
\(100-\left(1+\frac{1}{2}+\frac{1}{3}+.....+\frac{1}{100}\right)=\frac{1}{2}+\frac{2}{3}+\frac{3}{4}+...+\frac{99}{100}\)
Tính giá trị biểu thức sau :
\(A=\frac{\frac{16}{10}:\left(1\frac{3}{5}\times \frac{5}{4}\right)}{\frac{64}{100}-\frac{1}{25}}+\frac{\left(\frac{108}{100}-\frac{2}{25}\right):\frac{4}{7}}{\left(5\frac{5}{9}-2\frac{1}{4}\right)\times 2\frac{2}{17}}+\frac{3}{5}\times \frac{1}{2}:\frac{2}{5}\)
Tìm x \(1-\left(x\%+x:50+\frac{\frac{3}{2}-\frac{3}{7}-\frac{3}{13}}{\frac{25}{2}-\frac{25}{7}-\frac{25}{13}}\times x\right)=0\)
