a) \(\dfrac{3}{4}x=1\)
\(x=1:\dfrac{3}{4}\)
\(x=1.\dfrac{4}{3}\)
\(x=\dfrac{4}{3}\)
b)\(\dfrac{4}{7}x=\dfrac{9}{8}-0,125\)
\(\dfrac{4}{7}x=\dfrac{9}{8}-\dfrac{1}{8}\)
\(\dfrac{4}{7}x=1\)
\(x=1:\dfrac{4}{7}\)
\(x=1.\dfrac{7}{4}\)
\(x=\dfrac{7}{4}\)
a) \(\dfrac{3}{4}x=1\)
\(x=1:\dfrac{3}{4}=1.\dfrac{4}{3}\)
\(x=\dfrac{4}{3}\)
Vậy \(x=\dfrac{4}{3}\)
b) \(\dfrac{4}{7}x=\dfrac{9}{8}-0,125\)
\(\Leftrightarrow\dfrac{4}{7}x=\dfrac{9}{8}-\dfrac{1}{8}\)
\(\Rightarrow\dfrac{4}{7}x=1\)
\(x=1:\dfrac{4}{7}=1.\dfrac{7}{4}\)
\(x=\dfrac{7}{4}\)
Vậy \(x=\dfrac{7}{4}\)
