TÌM X BIẾT

 

3 phần 4 : x phần 6 = 0,75

Answer 1

\(\frac{3}{4}:\frac{x}{6}=0.75\)

\(\frac{3}{4}\cdot\frac{6}{x}=\frac{3}{4}\)

\(\frac{6}{x}=\frac{3}{4}:\frac{3}{4}\)

\(\frac{6}{x}=1\)

\(x=6\)

Answer 2

3/4 : x/6 = 0,75

        x/6 = 0,75 : 0,75 

        x/6 = 1 

        x   = 6

Answer 3

\(\frac{3}{4}:\frac{x}{6}=0,75\)

\(\frac{3}{4}:\frac{x}{6}=\frac{3}{4}\)

\(\frac{x}{6}=\frac{3}{4}:\frac{3}{4}\)

\(x:6=1\)

\(x=1x6\)

\(x=6\)

Vậy x = 6

Answer 4

\(\frac{3}{4}:\frac{x}{6}=0,75\)

\(\Rightarrow\frac{3}{4}.\frac{6}{x}=0,75\)

\(\Rightarrow\frac{18}{4x}=0,75\)

\(\Rightarrow x=\frac{18}{0,75}:4=6\)

Answer 5

X=6

Nha bạn 

Hok tốt

Answer 6

\(\frac{3}{4}:\frac{x}{6}=0,75\)

\(\frac{3}{4}.\frac{6}{x}=\frac{3}{4}\)

\(\frac{18}{4x}=\frac{3}{4}\)

\(\frac{9}{2x}=\frac{3}{4}\)

\(2x.3=9.4\)

\(6x=36\)

\(x=6\)

Answer 7

Ta có : 3/4 : x/6 = 0,75 .

⇒         3/4 : x/6 = 3/4 .

⇒                 x/6 = 3/4 : 3/4 .

⇒                 x/6 = 1 .

⇒                 x    = 6 .

Vậy x = 6 .

Answer 8

_{3 / 4 : X / 6 = 0 , 75} 

X / 6 = 3 / 4 : 0,75 

X / 6 = 1

X : 6 = 1

X = 6 X 1 

X = 6

Answer 9

\(\frac{3}{4}\cdot\frac{x}{6}=0,75\)

\(\frac{3}{4}\cdot\frac{x}{6}=\frac{3}{4}\)

         \(\frac{x}{6}=\frac{3}{4}:\frac{3}{4}\)

           \(\frac{x}{6}=1\)

Vậy x = 6 vì \(\frac{6}{6}=1\)
