-0,52 : x = -9,36 : 16,38

=> \(\frac{-0,52}{x}=\frac{-9,36}{16,38}\) 

=> x = \(\frac{-0,52.16,38}{-9,36}\) = 0,91

-0,52:x=-9,36:16,38

\(\frac{-0,52}{x}\)= \(\frac{-9,36}{16,38}\)

\(\Rightarrow\left(-0,52\right).16,38=x.\left(-9,36\right)\)

\(\Rightarrow x=\frac{-8,5176}{-9,36}\)

\(\Rightarrow x=0,91\)

\(Vậy,x=0,91\)

-0,52:x=-4/7

x=-0,52:-4/7

x=-13/25:-4/7

x=-13/25.-7/4

x=-91/100

vậy x=-91/100

\(-\dfrac{13}{25}:x=-\dfrac{4}{7}\)

\(x=-\dfrac{13}{25}:\left(-\dfrac{4}{7}\right)\)

\(x=-\dfrac{13}{25}.\left(-\dfrac{7}{4}\right)\)

\(x=\dfrac{91}{100}\)

Giải:

\(-0,52:x=-9,36:16,38\)

\(\Leftrightarrow-0,52.16,38=-9,36.x\)

\(\Leftrightarrow-9,36.x=-8,5176\)

\(\Leftrightarrow x=\dfrac{-8,5176}{-9,36}\)

\(\Leftrightarrow x=0,91\)

Vậy \(x=0,91\).

Chúc bạn học tốt!

0,52:x=-4/7

x=0,52:-4/7

x=-0,91=-91/100

-0,52:x=-9,36:16,38 

-0,52:x=-4/7

x=-0,52:4/7

x=0,91 nha Thai Duong

cho thằng này vào trại điên

-0,52:x= -936/100: 1638/100

-52/100:x=-4/7

           x= -52/100:-4/7

           x= 0,91

-0,52/x=-9,36:16,38

=>x.-9,36=-0,52.16,38

x.-9,36=-8,576

x         =8,576:9,36=0,91
