Question

\(\dfrac{3}{5}\) : \(\dfrac{1}{3}\) - \(\dfrac{1}{2}\) x \(\dfrac{2}{3}\)  giá trị biểu thức 

Answer 1

\(\dfrac{3}{5}:\dfrac{1}{3}-\dfrac{1}{2}\) x \(\dfrac{2}{3}\)

\(=\dfrac{3}{5}\) x \(\dfrac{3}{1}-\dfrac{1}{2}\) x \(\dfrac{2}{3}\)

\(=\dfrac{9}{5}-\dfrac{1}{2}\) x \(\dfrac{2}{3}\)

\(=\dfrac{9}{5}-\dfrac{1}{3}\)

\(=\dfrac{27}{15}-\dfrac{5}{15}\) 

\(=\dfrac{22}{15}\)

Answer 2

\(\dfrac{3}{5}:\dfrac{1}{3}-\dfrac{1}{2}\times\dfrac{2}{3}\\ =\dfrac{9}{5}-\dfrac{1}{3}\\ =\dfrac{22}{15}\)
