a) \(2\frac{2}{5}\cdot\frac{25}{18}=\frac{12}{5}\cdot\frac{25}{18}=\frac{300}{90}=\frac{10}{3}\)
b) \(\frac{9}{11}:2\frac{5}{2}\cdot2\frac{3}{4}=\frac{9}{11}.\frac{2}{9}\cdot\frac{11}{4}=\frac{1}{2}\)
c) \(10:\frac{35}{24}:\frac{36}{7}=10\cdot\frac{24}{35}\cdot\frac{7}{36}=\frac{4}{3}\)
d) \(10,77\cdot9,8+5,23\cdot9,8=9,8\cdot\left(10,77+5,23\right)=9,8\cdot16=156,8\)
e) \(1,26\cdot3,6:0,28-6,2=16,2-6,2=10\)

\(2\frac{2}{5}\) x \(\frac{25}{18}\) = \(\frac{12}{5}x\frac{25}{18}=\frac{10}{3}\) x = nhân
\(\frac{9}{11}:2\frac{5}{2}x2\frac{3}{4}\) = \(\frac{9}{11}:\frac{9}{2}x\frac{11}{4}=\frac{2}{11}x\frac{11}{4}=\frac{1}{2}\)
\(10:\frac{35}{24}:\frac{36}{7}=\frac{48}{7}:\frac{36}{7}=\frac{4}{3}\)
\(10,77x9,8+5,23x9,8=\left(10,77+5,23\right)x9,8=156,8\)
