\(=\left(\dfrac{11}{10}+\dfrac{7}{10}+\dfrac{1}{10}\right)+\left(\dfrac{17}{20}+\dfrac{9}{20}+\dfrac{3}{20}\right)\\ =\dfrac{19}{10}+\dfrac{29}{20}=\dfrac{19\times2}{10\times2}+\dfrac{29}{20}=\dfrac{38}{20}+\dfrac{29}{20}\\ =\dfrac{47}{20}\)
\(H=\left(\dfrac{11}{10}+\dfrac{7}{10}+\dfrac{1}{10}\right)+\left(\dfrac{17}{20}+\dfrac{9}{20}+\dfrac{3}{20}\right)\)
\(H=\dfrac{19}{10}+\dfrac{29}{20}\)
\(H=\dfrac{67}{20}\)
\(H=\dfrac{11}{10}+\dfrac{17}{20}+\dfrac{7}{10}+\dfrac{9}{20}+\dfrac{1}{10}+\dfrac{3}{20}\\ \Rightarrow H=\left(\dfrac{11}{10}+\dfrac{7}{10}+\dfrac{1}{10}\right)+\left(\dfrac{17}{20}+\dfrac{9}{20}+\dfrac{3}{20}\right)\\ \Rightarrow H=\dfrac{19}{10}+\dfrac{29}{20}\\ \Rightarrow H=\dfrac{38}{20}+\dfrac{29}{20}\\ \Rightarrow H=\dfrac{67}{20}\)
