Question

Tìm x biết :

4\(\dfrac{1}{3}\): \(\dfrac{x}{4}\)= 6: 0,3

Answer 1

4\(\dfrac{1}{3}\):\(\dfrac{x}{4}\)=6:0,3

=>\(\dfrac{13}{3}\):\(\dfrac{x}{4}\)=20

=>\(\dfrac{x}{4}\)=\(\dfrac{13}{3}\):20=\(\dfrac{13}{60}\)

=>x\(\in\varnothing\)

Answer 2

\(4\dfrac{1}{3}:\dfrac{x}{4}=6:0,3\)

\(\dfrac{13}{3}:\dfrac{x}{4}=20\)

\(\dfrac{x}{4}=20.\dfrac{13}{3}\)

\(\dfrac{x}{4}=\dfrac{260}{3}\)

\(\dfrac{3x}{12}=\dfrac{1040}{12}\)

\(3x=1040\)

\(x=1040:3\)

\(x=\dfrac{1040}{3}\)

Answer 3

\(4\dfrac{1}{3}:\dfrac{x}{4}=6:0.3\\ \dfrac{13}{3}:\dfrac{x}{4}=20\\ x:4=\dfrac{13}{3}:20\\ x=\dfrac{13}{60}\cdot4\\ x=\dfrac{13}{15}\) tất cả sai hết
