Question

0,3*(x*1/3)=1/2*(0,81:2,7)

Answer 1

\(0,3.\left(x.\frac{1}{3}\right)=\frac{1}{2}.\left(0,81:2,7\right)\)

\(0,3.\left(x.\frac{1}{3}\right)=\frac{1}{2}.\frac{3}{10}\)

\(0,3.\left(x.\frac{1}{3}\right)=\frac{3}{20}\)

\(\frac{1}{3}x=\frac{3}{20}:0,3\)

\(\frac{1}{3}x=\frac{1}{2}\)

\(x=\frac{1}{2}:\frac{1}{3}\)

\(x=\frac{3}{2}\)

Vậy x = 3/2

Answer 2

Answer 3

x=3/2

Answer 4

\(0,3\cdot\left(x\cdot\frac{1}{3}\right)=\frac{1}{2}\cdot\left(0.,1:2,7\right)\)

\(0,3\cdot\left(x\cdot\frac{1}{3}\right)=\frac{1}{2}\cdot0,3\)

\(0,3\cdot\left(x\cdot\frac{1}{3}\right)=0,15\)

\(\left(x\cdot\frac{1}{3}\right)=0,15:0,3\)

\(\left(x\cdot\frac{1}{3}\right)=0,5\)

\(x=0,5:\frac{1}{3}\)

\(x=1,5\)

kb và cho mk nha

Answer 5

\(0.3\left(x\cdot\frac{1}{3}\right)=\frac{1}{2}\cdot\left(0,18:2,7\right)\)

\(0.3\cdot\left(x\cdot\frac{1}{3}\right)=\frac{1}{2}\cdot0,3\)

\(0,3\left(x\cdot\frac{1}{3}\right)=0,15\)

\(\left(x\cdot\frac{1}{3}\right)=0,15:0,3\)

\(\left(x\cdot\frac{1}{3}\right)=0,5\)

\(x=0,5:\frac{1}{3}\)

\(x=1,5\)
