\(\frac{3}{4}x\frac{5}{6}-\frac{1}{6}=\frac{11}{24}\)

\(4\frac{8}{5}-\frac{2}{3}=\frac{28}{5}-\frac{2}{3}=\frac{74}{15}\)

\(\frac{3}{4}\times x+\frac{5}{3}\times x=\frac{7}{12}\)

\(\left(\frac{3}{4}+\frac{5}{3}\right)\times x=\frac{7}{12}\)

\(\frac{29}{12}\times x=\frac{7}{12}\)

\(x=\frac{7}{12}\div\frac{29}{12}\)

\(x=\frac{7}{29}\)

\(\frac{\frac{3}{4}-\frac{5}{3}}{x}=\frac{7}{12}\Rightarrow x=\left(\frac{3}{4}-\frac{5}{3}\right):\frac{7}{12}=-\frac{11}{12}:\frac{7}{12}=-\frac{11}{12}.\frac{12}{7}=-\frac{11}{7}\)

35/6+x=3/4x51/2

35/6+x=153/8

         x=153/8-35/6

          x=319/24

\(\frac{35}{6}+X=\frac{3}{4}\times5\frac{1}{2}\)

 \(\frac{35}{6}_{ }+X=\frac{33}{8}\)

              \(X=\frac{33}{8}-\frac{35}{6}\)

             \(X=\frac{-41}{24}\)

3/4 - (x - 3) × 2 = 3 1/3 + 2

3/4 - (x - 3) × 2 = 10/3 + 2

3/4 - (x - 3) × 2 = 16/3

(x - 3) × 2 = 3/4 - 16/3

(x - 3) × 2 = -55/12 (lớp 5 chưa học số âm)

Em xem lại đề nhé

a: \(=\dfrac{3\cdot\left(6+4\right)}{6\cdot2}=\dfrac{3\cdot10}{6\cdot2}=\dfrac{30}{12}=\dfrac{5}{2}\)

b: \(=\dfrac{12\left(6-1\right)}{3\left(4+5\right)}=4\cdot\dfrac{5}{9}=\dfrac{20}{9}\)

\(3\frac{1}{2}+4\frac{5}{7}-5\frac{5}{14}=\frac{7}{2}+\frac{33}{7}-\frac{75}{14}=\frac{49}{14}+\frac{66}{14}-\frac{75}{14}=\frac{40}{14}=\frac{20}{7}\)
