Question

tìm x 
x x 11 = 33/20 
5 : x = 4/7

Answer 1

\(x\times11=\dfrac{33}{20}\)

\(x=\dfrac{33}{20}:11\)

\(x=\dfrac{3}{20}\)

 

\(5:x=\dfrac{4}{7}\)

     \(x=5:\dfrac{4}{7}\)

     \(x=\dfrac{35}{4}\)

Answer 2

`x xx 11 = 33 / 20`

`x = 33 / 20 : 11`

`x = 33 / 20 . 1 / 11`

`x = 3 / 20`             Vậy `x = 3 / 20`

_______________________________

`5 : x = 4 / 7`

`x = 5 : 4 / 7`

`x = 5 . 7 / 4`

`x = 35 / 4`            Vậy `x = 35 / 4`

Answer 3

`x xx 11 = 33/20`

`x = 33/20 : 11`

`x = 1/20`

______________

`5 : x = 4/7`

`x = 5 : 4/7`

`x = 35/4`

Answer 4

\(X\times11=\dfrac{33}{20}\)

\(x=\dfrac{33}{20}:11\)

\(x=\dfrac{3}{20}\)

\(5:x=\dfrac{4}{7}\)

\(x=5:\dfrac{4}{7}\)

\(x=\dfrac{35}{4}\)

 

Answer 5

3/20

35/4
