Bài 1: Tìm x, biết
a) \(\frac{-2,6}{x}=\frac{-12}{42}\)
b) \(\frac{x}{\frac{1}{3}}=\frac{\frac{1}{6}}{\frac{2}{3}}\)
c) \(2\frac{\frac{2}{3}}{0,03}=1\frac{\frac{7}{9}}{x}\)
d) \(\frac{x-2}{5}=\frac{3}{8}\)
e) \(\frac{24}{25}=\frac{x^2}{6}\)
f) \(\frac{x-1}{x+5}=\frac{6}{7}\left(x\ne5\right)\)
g) \(0,6\div x=x\div2,4\)
