Question

x + x / 0,2 = 1,35 

ai nhanh mk tk

Answer 1

= 0,135 đúng không bạn tích nha

Answer 2

x =0,225

Answer 3

\(x+\frac{x}{0,2}=1,35\)

\(\frac{x\times0,2+x}{0,2}=1,35\)

\(\frac{1,2\times x}{0,2}=1,35\)

\(1,2\times x=1,35\times0,2\)

\(1,2\times x=0,27\)

\(x=0,27:1,2\)

\(x=0,225\)

Answer 4

x + x :1/5 = 1,35

x + x . 5 = 1,35

x .(5+1) = 1.35

x . 6 = 1,35

     x =1,35 : 6

     x = 0,225
