Tính \(1\frac{1}{2}+2\frac{2}{3}+3\frac{3}{4}+4\frac{4}{5}+...+50\frac{50}{51}+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{51}\)
Tính: \(1\frac{1}{2}+2\frac{2}{3}+3\frac{3}{4}+...+50\frac{50}{51}+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{51}\)= ________?
\(\frac{2^2}{1.3}.\frac{3^2}{2.4}.\frac{4^2}{3.5}...\frac{50^2}{49.51}\) tính
giải giúp mình nha
\(1\frac{1}{2}+2\frac{2}{3}+3\frac{3}{4}+...+50\frac{50}{51}+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...\frac{1}{51}\)
Tính hợp lí: \(\frac{4}{5}.50\frac{1}{2}+\frac{2}{3}.41\frac{7}{5}-\frac{5}{4}.40\frac{1}{2}+\frac{2}{3}.\frac{2}{7}\)
e, \(\frac{49}{1}+\frac{48}{2}+\frac{47}{3}+.......+\frac{2}{48}+\frac{1}{49}=50.\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+.......+\frac{1}{50}\right)\)
\(x=\frac{y}{3};\frac{y}{2}=\frac{2}{5}vàx+y+z=50\)
đang cần gấp nhanh nha,kb vs mik ^_^
\(-2\frac{1}{5}\&\frac{110}{-50};\frac{17}{20}\&0,75\)
