\(6\div\left(-27\right)=\left(-6\frac{1}{2}\right)\div29\frac{1}{4}\)

\(6×\frac{-1}{27}=\frac{-13}{2}\div\frac{117}{4}\)

\(\frac{-2}{9}=\frac{-13}{2}×\frac{4}{117}\)

\(\frac{-2}{9}=\frac{-52}{234}\)

\(\Rightarrow\)\(\frac{9}{-2}=\frac{234}{-52}\)

\(\frac{-2}{-52}=\frac{9}{234}\)

\(\frac{-52}{-2}=\frac{234}{9}\)

Vậy, ...

Cbht

Từ \(6:(-27)=\left[-6\frac{1}{2}\right]:29\frac{1}{4}\Rightarrow6\cdot29\frac{1}{4}=(-27)\left[-6\frac{1}{2}\right]\)

Áp dụng tính chất của tỉ lệ thức ta suy ra :

\(\frac{6}{-6\frac{1}{2}}=\frac{-27}{29\frac{1}{4}};\frac{-6\frac{1}{2}}{6}=\frac{29\frac{1}{4}}{-27};\frac{-27}{6}=\frac{29\frac{1}{4}}{-6\frac{1}{2}};\frac{6}{-27}=\frac{-6\frac{1}{2}}{29\frac{1}{4}}\)

Thông cảm Thạnh Super Ngu dấu ngoặc đơn mình bấm không được nên mk bấm dấu ngoặc vuông nhé.

\(6:\left(-27\right)=\left(-6\frac{1}{2}\right):29\frac{1}{4}\)

các tỉ lệ thức là:

\(\frac{6}{-27}=\frac{-6\frac{1}{2}}{29\frac{1}{4}};\frac{-27}{6}=\frac{29\frac{1}{4}}{-6\frac{1}{2}};\frac{6}{-6\frac{1}{2}}=\frac{-27}{29\frac{1}{4}};\frac{-6\frac{1}{2}}{6}=\frac{29\frac{1}{4}}{-27}\)

6:(-27)=(\(-6\dfrac{1}{2}\))\(:29\dfrac{1}{4}\)

\(\Leftrightarrow\)6:(-27)=\(\left(-\dfrac{13}{2}\right):\dfrac{117}{4}\)

\(\Rightarrow\)\(\left(-\dfrac{13}{2}\right):\dfrac{117}{4}\)=\(\left(-\dfrac{13}{2}\right):\dfrac{4}{117}\)=\(-\dfrac{2}{9}\)

Ta có:\(\dfrac{6}{-27}=\dfrac{-2}{9}\)

hay\(\dfrac{6}{-2}=\dfrac{-27}{9}\);\(\dfrac{6}{-2}=\dfrac{27}{-9}\);\(\dfrac{2}{-9}=\dfrac{6}{-27}\)

29/1/4=117/4

6/1/2=13/2

suy ra      các tỉ lệ thức là:6/27=117/4/13/2 ;-6/13/2 =117/4/-27 và đảo mẫu với tử nữa nhé

thấy hợp lý thì k cho mình nha

\(\dfrac{6}{-6,5}=\dfrac{29,25}{-27};\dfrac{6,5}{6}=\dfrac{-27}{29,25}\)

\(\dfrac{6}{-6\dfrac{1}{2}}=\dfrac{29\dfrac{1}{4}}{-27};\dfrac{6}{29\dfrac{1}{4}}=\dfrac{-6\dfrac{1}{2}}{-27};\dfrac{-6\dfrac{1}{2}}{6}=\dfrac{-27}{29\dfrac{1}{4}};\dfrac{29\dfrac{1}{4}}{6}=\dfrac{-27}{-6\dfrac{1}{2}}\)
