Answer 1

\(\dfrac{10}{3}-\dfrac{4}{3}:\dfrac{5}{6}-\dfrac{7}{3}=\dfrac{6}{3}:\dfrac{9}{6}=2:\dfrac{3}{2}=\dfrac{3}{4}\)

Answer 2

a)

= 10/3 - 4/3 : 5/6 - 7/3

= 10/3 - 8/5 - 7/3

= 26/15 - 7/3

= -3/5

Chúc bạn học tốt!! ^^

Answer 3

\(3\dfrac{1}{3}-1\dfrac{1}{3}:\dfrac{5}{6}-2\dfrac{1}{3}\)

\(=\dfrac{10}{3}-\dfrac{4}{3}:\dfrac{10}{6}-\dfrac{7}{3}\)

\(=\left(\dfrac{10}{3}-\dfrac{7}{3}\right)-\dfrac{4}{5}\)

\(=1-\dfrac{4}{5}\)

\(=\dfrac{1}{5}\)

Answer 4

\(3\dfrac{1}{3}-1\dfrac{1}{3}:\dfrac{5}{6}-2\dfrac{1}{3}\)

\(=1-\dfrac{4}{3}\cdot\dfrac{6}{5}\)

\(=1-\dfrac{8}{5}=\dfrac{-3}{5}\)
