Question

\(\frac{2}{15}\)* \(\frac{3}{x}\)= \(\frac{-70}{21}\)

tim x nhanh giùm mk nha

ai nhanh mk tick cho

 

Answer 1

\(\frac{2}{15}\cdot\frac{3}{x}=-\frac{70}{21}\)

\(\frac{3}{x}=-\frac{70}{21}:\frac{2}{15}\)

\(\frac{3}{x}=-25\)

\(x=3:\left(-25\right)=-\frac{3}{25}\)

Answer 2

\(\frac{3}{x}=\frac{-70}{21}\div\frac{2}{15}\)

\(\frac{3}{x}=-25\)

\(\Rightarrow x=\frac{-3}{25}\)
