Tìm \(x\), biết:

\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)

Help!

Answer 1

\(\frac{X}{126}=\frac{-7}{24}.\frac{-6}{11}\)

\(\frac{X}{126}=\frac{42}{264}\)

\(\frac{X}{126}=\frac{7}{44}\)

\(X=\frac{7}{44}.126=\frac{882}{44}=\frac{441}{22}\)

Vậy x = 441/22

Answer 2

\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)

\(\Rightarrow\frac{x}{126}=\frac{7}{44}\)

\(\Rightarrow x.44=126.7\)

\(\Rightarrow x.44=882\)

\(\Rightarrow x=882:44\)

\(\Rightarrow x=\frac{441}{22}\)
