Answer 1

\(e,=\left(\dfrac{11}{5}+\dfrac{4}{5}\right)-\left(\dfrac{4}{13}+\dfrac{9}{13}\right)+\left(\dfrac{30}{7}-\dfrac{2}{7}\right)=3-1+4=6\\ f,=\dfrac{13}{5}\cdot\dfrac{11}{24}-\dfrac{13}{5}\cdot\dfrac{1}{2}-\dfrac{13}{5}\cdot\dfrac{5}{3}\\ =\dfrac{13}{5}\left(\dfrac{11}{24}-\dfrac{1}{2}-\dfrac{5}{3}\right)=-\dfrac{41}{24}\cdot\dfrac{13}{5}=-\dfrac{533}{120}\\ g,=8+3\cdot1-\dfrac{1}{4}\cdot4+4\cdot2\cdot\dfrac{1}{8}=8+3-1+1=11\\ h,=\dfrac{4}{5}\cdot\dfrac{5}{4}+\dfrac{4}{9}\cdot\dfrac{9}{4}+\dfrac{1}{8}=1+1+\dfrac{1}{8}=\dfrac{17}{8}\)
