\(\dfrac{4}{3}.\dfrac{9}{5}-\dfrac{3}{10}\)
\(=\dfrac{4}{3}.\dfrac{3}{2}\)
\(=2\)
\(\dfrac{15}{14}:\dfrac{10}{21}.\dfrac{1}{5}\)
\(=\dfrac{9}{4}.\dfrac{1}{5}\)
\(=\dfrac{9}{20}\)
\(5.\dfrac{1}{5}+\dfrac{1}{5}\)
\(=1+\dfrac{1}{5}\)
\(=\dfrac{6}{5}\)
\(7:\dfrac{1}{5}-\dfrac{1}{5}\)
\(=35-\dfrac{1}{5}\)
=\(=\dfrac{174}{5}\)
