Question

tìm x biết

0,32 : x = 5-3,4

Answer 1

0,32 : x = 5 - 3,4

=> 0,32 : x = 1,6

=>           x = 0,32 : 1,6

=>           x = 0,2

Answer 2

0,32 : x = 5 - 3,4 

=> 8/25 : x = 8/5

=>  x = 8/25 : 8/5 

=> x = 8/25 . 5/8

=> x = 1/5

Vậy ...

Answer 3

\(0.32\div x=5-3.4\)

\(\Rightarrow0.32\div x=1.6\)

\(\Rightarrow x=0.32\div1.6\)

\(\Rightarrow x=0.2\)
