Question

Tìm x

4/5 + 5/7 : x = 1/6

Giúp em với ạ

Answer 1

4/5 + 5/7 : x = 1/6

=> 5/7 : x = -19/30

=> x = -150/133

Answer 2

5/7:x=1/6-4/5

5/7:x=-19/30

      x=5/7:(-19/30)

      x=-150/133

vậy x=-150/133

Answer 3

4/5 + 5/7:x =1/6

         5/7 :x= -19/30

               x= -150/133

Answer 4

4/5 + 5/7 : x = 1/6

=>  5/7:x=4/5-1/6

=>  5/7:x=24/30-5/30

=>  5/7:x=19/30

=>  x=5/7:19/30

=>  x=5/7.30/19

=>  x=150/133

Answer 5

4/5 + 5/7 : x = 1/6

5/7 : x = 1/6 - 4/5

5/7 : x = 5/30 - 24/30

5/7 : x = -19/30

x = 5/7 : (-19/30)

x = 5/7 x (-30/19)

x = -155/133

Vậy x = -150/133

Answer 6

làm lại :

4/5 + 5/7 : x = 1/6

=>  5/7:x=1/6-4/5

=>  5/7:x=5/30-24/30

=>  5/7:x=-19/30

=>  x=5/7:(-19)/30

=>  x=5/7.30/-19

=>  x=-150/133

Answer 7

\(\frac{4}{5}+\frac{5}{7}\div X=\frac{1}{6}\Rightarrow\)\(\frac{5}{7}\div X=\frac{1}{6}-\frac{4}{5}\Rightarrow\)\(\frac{5}{7}\div X=\frac{-19}{30}\Rightarrow\)\(X=\frac{5}{7}\div\frac{-19}{30}\Rightarrow\)\(X=\frac{5}{7}\times\frac{-30}{19}\Rightarrow\)\(X=\frac{-150}{133}\)
