a: \(=\dfrac{-3}{4}\left(15+\dfrac{2}{3}+24+\dfrac{1}{3}\right)=\dfrac{-3}{4}\cdot40=-30\)
b: \(=\dfrac{3}{8}\left(27+\dfrac{1}{5}-3-\dfrac{1}{5}\right)+19=\dfrac{3}{8}\cdot24+19=9+19=28\)
c: \(=\dfrac{7}{10}\cdot\dfrac{4}{5}+\dfrac{4}{5}\cdot\dfrac{3}{10}=\dfrac{4}{5}\)
d: \(=\dfrac{4}{15}+\dfrac{11}{15}+\dfrac{7}{11}+\dfrac{4}{11}-3.25=2-3.25=-1.25\)
f: \(=\dfrac{3}{5}\left(16+\dfrac{1}{4}-6-\dfrac{1}{4}\right)+\left|\dfrac{15-16}{10}\right|\)
\(=\dfrac{3}{5}\cdot10+\dfrac{1}{10}=6+\dfrac{1}{10}=\dfrac{61}{10}\)
