\(3\frac{1}{3}x+16\frac{3}{4}=-19\frac{1}{4}\)

\(\frac{10}{3}x+\frac{67}{4}=\frac{-77}{4}\)

\(\frac{10}{3}x=\frac{-77}{4}-\frac{67}{4}\)

\(\frac{10}{3}x=-36\)

\(x=\left(-36\right):\frac{10}{3}\)

\(x=\frac{-54}{5}\)

\(3\frac{1}{3}x+16\frac{3}{4}=-19\frac{1}{4}\)

\(\Rightarrow\)\(\frac{10}{3}x+\frac{67}{4}=-\frac{77}{4}\)

\(\Rightarrow\)\(\frac{10}{3}x=-\frac{77}{4}-\frac{67}{4}\)

\(\Rightarrow\)\(\frac{10}{3}x=-36\)

\(\Rightarrow\)\(x=-36\times\frac{3}{10}\)

\(\Rightarrow\)\(x=-\frac{54}{5}\)

\(x:4\frac{1}{3}=-2,5\)

\(x:\frac{13}{3}=\frac{-5}{2}\)

\(x=\frac{-5}{2}.\frac{13}{3}\)

\(x=\frac{-65}{6}\)

Hình như đề thiếu ý bn ak ! Bn xem lại đề xg mik làm cho

Ta có :

M1 = 3 + 1/2 - 2/3

M1 = 17/6

M2 = 3 + 2/3 - 5/6

M2 = 17/6 

=> M = \(\frac{\frac{17}{6}}{\frac{17}{6}}\)

=> M = ( 17 : 6 ) : ( 17 : 6 )

=> M = 1

19,04 : 5,6 = 3,4

637,38 : 18 = 35,41

56,32 x 2,4 = 135,168

19,04 : 5,6 = 3,4

637,38 : 18 = 35,41

56,32 x 2,4 = 135,168

CHị tham khảo nhé 

1+1+1+1+1 = 5

1+1+1+1+1=5

tk cho mk nha

Đề thiếu.

\(\frac{2}{3}+\frac{1}{3}:3x=20\%\)

\(\frac{2}{3}+\frac{1}{9}x=\frac{1}{5}\)

\(\frac{1}{9}x=\frac{1}{5}-\frac{2}{3}\)

\(\frac{1}{9}x=\frac{-7}{15}\)

\(x=\frac{-7}{15}:\frac{1}{9}\)

\(x=\frac{-21}{5}\)

\(\frac{2}{3}+\frac{1}{3}:3x=20\%\)

\(< =>\frac{1}{3}:3x=20\%-\frac{2}{3}\)

\(< =>\frac{1}{3}:3x=\frac{-7}{15}\)

\(< =>3x=\frac{-5}{7}\)

\(< =>x=\frac{-5}{21}\)
