Question

0,16 : x+ 2/5=2

Answer 1

\(0.16:x+\frac{2}{5}=2\)

\(\frac{4}{25}:x+\frac{2}{5}=2\)

\(\frac{4}{25}:x=2-\frac{2}{5}\)

\(\frac{4}{25}:x=\frac{8}{5}\)

\(x=\frac{4}{25}:\frac{8}{5}\)

\(x=\frac{1}{10}\)

Answer 2

x = 1 nha bn

Answer 3

\(0,16:x+\frac{2}{5}=2\)

\(\Rightarrow\frac{4}{25}:x=2-\frac{2}{5}\)

\(\Rightarrow\frac{4}{25}:x=\frac{8}{5}\)

\(\Rightarrow x=\frac{4}{25}:\frac{8}{5}\)

\(\Rightarrow x=\frac{1}{10}\)

Vậy  \(x=\frac{1}{10}\)

Answer 4

0,16 : x + 0,4 = 2 

=> 0,16 : x = 2 - 0,4 

=> 0,16 : x  = 1,6

=> x = 0,16 : 1,6 

=> x = 0,1

Vậy x = 0,1 

Answer 5

\(0,16\text{ : }x+\frac{2}{5}=2\)

\(0,16\text{ : }x=2-\frac{2}{5}\)

\(0,16\text{ : x }=\frac{8}{5}\)

\(\Leftrightarrow x=0,16\text{ : }\frac{8}{5}\)

\(\Leftrightarrow x=\frac{4}{25}\text{ : }\frac{8}{5}\)

\(\Leftrightarrow x=\frac{4}{25}\text{ }\cdot\frac{5}{8}\)

\(\Leftrightarrow x=\frac{1}{10}\)

Answer 6

X=1/10 nha bạn.
