Question

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

mk can gap ai nhanh dung nhat thi mk tick

 

Answer 1

\(\frac{4}{5}+\frac{5}{7}:x=\frac{1}{6}\)

\(\Leftrightarrow\frac{5}{7}:x=\frac{1}{6}-\frac{4}{5}\)

\(\Rightarrow\frac{5}{7}:x=\frac{5}{30}-\frac{24}{30}\)

\(\Rightarrow\frac{5}{7}:x=-\frac{19}{30}\)

\(\Rightarrow x=-\frac{19}{30}:\frac{5}{7}=-\frac{19}{30}\cdot\frac{7}{5}=-\frac{133}{150}\)

Answer 2

\(=>\frac{5}{7}:x=\frac{1}{6}-\frac{4}{5}\)

\(=>\frac{5}{7}:x=\frac{-19}{30}\)

\(=>x=\frac{5}{7}:\frac{-19}{30}\)

\(=>x=\frac{-150}{133}\)

Answer 3

dễ thế mà không làm được

Answer 4

 4/5 + 5/7 : x = 1/6

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

5/7 : x = 29/30

x = 29/30 . 5/7

x = 145/210 = 29/42 

Học tốt!

Answer 5

                     Bài làm

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 = -19/30 . 5/7

=> x = -19/42

Chúc ban hc tốt

Answer 6

\(\frac{4}{5}+\frac{5}{7}:x=\frac{1}{6}\)

\(\frac{5}{7}:x=\frac{1}{6}-\frac{4}{5}\)

\(\frac{5}{7}:x=\frac{-19}{30}\)

\(x=\frac{5}{7}:\frac{-19}{30}\)

\(x=\frac{-150}{133}\)

Answer 7

\(=>\frac{5}{7}:x=\frac{1}{6}-\frac{4}{5}\)

\(=>\frac{5}{7}:x=\frac{-19}{30}\)

=>\(x=\frac{5}{7}:\frac{-19}{30}\)

=>\(x=\frac{-150}{133}\)
