\(\frac{13}{3}:\frac{x}{4}=6:0,3\)
\(\frac{13}{3}:\frac{x}{4}=20\)
\(\frac{x}{4}=\frac{13}{3}:20\)
\(\frac{x}{4}=\frac{13}{60}\)
x.60:=4.13
x.60=52
x=52:60
\(x=\frac{13}{15}\)
vậy \(x=\frac{13}{15}\)
\(4\frac{1}{3}:\frac{x}{4}=6:0,3\)
\(\Rightarrow\frac{13}{3}.\frac{4}{x}=20\)
\(\Rightarrow\frac{4}{x}=\frac{60}{13}\)
\(\Leftrightarrow60x=13.4=52\)
\(\Leftrightarrow x=\frac{13}{15}\)
\(1\frac{2}{3}:\frac{x}{4}=6:0,3\)
\(\frac{5}{3}:\frac{x}{4}=20\)
\(\Rightarrow\frac{x}{4}=\frac{5}{3}:20\)
\(\Rightarrow\frac{x}{4}=\frac{1}{12}\Rightarrow x=\frac{4}{12}=\frac{1}{3}\)
a) \(\frac{-3}{7}+x=\frac{1}{3}\)
\(\Leftrightarrow x=\frac{1}{3}+\frac{3}{7}\)
\(\Leftrightarrow x=\frac{16}{21}\)
b) \(\frac{-5}{8}+x=\frac{-2^2}{3}\)
\(\Leftrightarrow x=\frac{-4}{3}+\frac{5}{8}\)
\(\Leftrightarrow x=-\frac{17}{24}\)
c) \(4\frac{1}{3}:\frac{x}{4}=6:0,3\)
\(\Leftrightarrow\frac{8}{3}:\frac{x}{4}=20\)
\(\Leftrightarrow\frac{32}{3x}=20\)
\(\Leftrightarrow3x=\frac{8}{5}\)
\(\Leftrightarrow x=\frac{8}{15}\)
\(1\frac{2}{3}:\frac{x}{4}=6:0,3\)
\(\frac{5}{3}:\frac{x}{4}=20\)
\(\frac{x}{4}=\frac{5}{3}:20\)
\(\frac{x}{4}=\frac{1}{12}\)
\(\Rightarrow\frac{3x}{12}=\frac{1}{12}\)
\(\Rightarrow3x=1\)
\(\Rightarrow x=\frac{1}{3}\)
Vậy \(x=\frac{1}{3}\)
\(\frac{13}{3}:\frac{x}{4}=6:0,3\)
\(\frac{13}{3}:\frac{x}{4}=20\)
\(\frac{x}{4}=\frac{13}{3}:20\)
\(\frac{x}{4}=\frac{13}{3.20}\)
\(\frac{x}{4}=\frac{13}{60}\)
\(60x=13.4\)
\(60x=52\)
\(x=\frac{52}{60}\)
\(x=\frac{13}{15}\)
Vậy \(x=\frac{13}{15}\)
