Question

2/3+1/3 : 3x =3/4

giúp mình với

Answer 1

\(\dfrac{2}{3}+\dfrac{1}{3}:3x=\dfrac{3}{4}\)

\(\dfrac{1}{3}:3x=\dfrac{3}{4}-\dfrac{2}{3}\)

\(\dfrac{1}{3}:3x=\dfrac{1}{12}\)

\(3x=\dfrac{1}{3}:\dfrac{1}{12}\)

\(3x=4\)

\(x=4:3\)

\(x=\dfrac{4}{3}\)

Answer 2

\(\dfrac{2}{3}+\dfrac{1}{3}:3x=\dfrac{3}{4}\)

\(\dfrac{1}{3}:3x=\dfrac{3}{4}-\dfrac{2}{3}\)

\(\dfrac{1}{3}:3x=\dfrac{1}{12}\)

\(3x=\dfrac{1}{3}:\dfrac{1}{12}\)

\(3x=4\)

\(x=\dfrac{4}{3}\)

Answer 3

\(\dfrac{2}{3}+\dfrac{1}{3}:3x=\dfrac{3}{4}\\ \dfrac{1}{3}:3x=\dfrac{3}{4}-\dfrac{2}{3}\\ \dfrac{1}{3}:3x=\dfrac{1}{12}\\ 3x=\dfrac{1}{3}:\dfrac{1}{12}\\ x=\dfrac{4}{3}\)
