giải chi tiết giúp mình nhé thank you very much
\(A=\frac{4}{10\cdot2}+\frac{6}{2\cdot20}+\frac{15}{5\cdot20}+\frac{5}{5\cdot40};B=\frac{3}{1\cdot5}+\frac{5}{13\cdot1}+\frac{11}{13\cdot3}+\frac{2}{3\cdot26}\)
So sánh A với B
a,\(\frac{2}{3}\cdot\left(\frac{1}{3}+\frac{2}{5}\right)\)
b,24+25+26+.....+99+100
c,\(\frac{16\cdot17-5}{16\cdot16+11}\)
d,\(\frac{5}{80}+\frac{5}{90}+\frac{5}{150}+\frac{5}{210}+\frac{5}{270}\)
$\frac{\frac{\frac{15}{6.16}+\frac{15}{16.26}+\frac{15}{26.36}}{33}}{6.16}-\frac{63}{16.26}+\frac{93}{26.36}$
