\(1-\dfrac{1}{2}+\dfrac{1}{3}=1-\left(\dfrac{6}{3}+\dfrac{2}{3}\right)\)
\(=1-\dfrac{8}{3}=\dfrac{-5}{3}\)

\(x.\dfrac{3}{4}=\dfrac{1}{5}.\dfrac{9}{8}\)
\(x.\dfrac{3}{4}=\dfrac{9}{40}\)
\(x=\dfrac{9}{40}:\dfrac{3}{4}\)
\(x=\dfrac{3}{10}\)
Vậy \(x=\dfrac{3}{10}\)

\(\dfrac{10}{3}:\dfrac{17}{4}=\dfrac{10}{3}.\dfrac{4}{17}=\dfrac{10.4}{3.17}=\dfrac{40}{51}\)

\(100-94+90-84+80-74+70-64+60-54\)
\(=6+6+6+6+6\)
\(=6.5=30\)

\(100-94+90-84+80-74+70-64+60-54\)
\(=6+6+6+6+6\)
\(=6^5=30\)
