2:
a: \(=\left(\dfrac{36}{4}-\dfrac{2}{4}-\dfrac{3}{4}\right):\left(\dfrac{56}{8}-\dfrac{2}{8}-\dfrac{5}{8}\right)\)
\(=\dfrac{31}{4}:\dfrac{49}{8}\)
\(=\dfrac{31}{4}\cdot\dfrac{8}{49}=\dfrac{62}{49}\)
b: \(=\dfrac{31}{3}-\dfrac{1}{2}-\dfrac{2}{3}+\dfrac{1}{2}=\dfrac{31}{3}-\dfrac{2}{3}=\dfrac{29}{3}\)
c: \(=\dfrac{7}{6}\left(\dfrac{13}{4}-\dfrac{1}{4}\right)=\dfrac{7}{6}\cdot3=\dfrac{7}{2}\)
d: \(=564:\left(\dfrac{12\left(1+\dfrac{1}{7}-\dfrac{1}{25}-\dfrac{1}{71}\right)}{4\left(1+\dfrac{1}{7}-\dfrac{1}{25}-\dfrac{1}{71}\right)}:\dfrac{3\left(1+\dfrac{1}{13}+\dfrac{1}{19}+\dfrac{1}{101}\right)}{5\left(1+\dfrac{1}{13}+\dfrac{1}{19}+\dfrac{1}{101}\right)}\right)\)
\(=564:\left(3\cdot\dfrac{5}{3}\right)=\dfrac{564}{5}\)
