lấy 94 : 47 = 2; 2 x 105 = 210

94:x=47/105

x=47/105:94

x=1/210

\(94:x=\frac{47}{105}\)

\(x=\frac{47}{105}:\frac{94}{1}\)

\(x=\frac{47}{105}\cdot\frac{1}{94}\)

\(x=\frac{47}{9870}=\frac{1}{210}\)

bài này rất dễ

\(94:x=\frac{47}{105}\)

          \(x=94:\frac{47}{105}\)

          \(x=94\times\frac{105}{47}\)

          \(x=210\)

94 : x = 47/105

=> x = 94 : 47/105

=> x = 94 * 105/47

=> x = 210

94:x=47/105

=>94/x=47/105

=>94*105=47x

=>9870=47x

=>x=9870:47

=>x=210

94 : x = 47/105

       x = 94 : 47/105

       x =   210

94 : x = 47/105

=> x = 210

x=94:47/105

x=94x105/47

x=210

94 : x = 47/105

      x = 94 : 47/105

       x = 94 . 105/47

       x = .......?

x=94:47/105                                                                                                                                                   x=210

\(94:x=\frac{47}{105}\)

\(x=94:\frac{47}{105}\)

\(x=\frac{94x105}{47}\)

\(x=\frac{47x2x105}{47}=2x105=210\)

Vậy x=210

ta có: 94/x=47/105

         94/x=47.2/105.2

         94/x=94/210

         => x=210

Ta có : 94 : x = 47 / 105

=> x = 94 : 47 / 105 

=> x = 210

bang 210

x=94:47/105

x=94*105/47

x=9870/47

x=210

* là nhân nha bạn

x=94/47/105=210 nha bạn!!!!!!!!!!!

\(\frac{47}{105}=\frac{94}{x}\Leftrightarrow47.x=105.94\Rightarrow x=\frac{105.94}{47}=\frac{9870}{47}=210\)

Vậy x = 210

x = 94 : 47/105 

x = 1410

duyệt nha

x=94.105:47=2002,34

Ta có:94:x=\(\frac{47}{105}\)

       x=94:\(\frac{47}{105}\)

       x=210

      Đáp số:210
