a) \(\frac{7}{15}+x\cdot\frac{5}{6}=\frac{2}{3}\)
=> \(\frac{7}{15}+x=\frac{2}{3}-\frac{5}{6}=-\frac{1}{6}\)
=> \(x=-\frac{1}{6}-\frac{7}{15}=-\frac{19}{30}\)
b) \(x:\frac{5}{6}-\frac{1}{3}=\frac{7}{12}\)
=> \(x:\frac{5}{6}=\frac{7}{12}+\frac{1}{3}=\frac{11}{12}\)
=> \(x=\frac{11}{12}\cdot\frac{5}{6}=\frac{55}{72}\)
c) \(\frac{11}{15}-x:\frac{1}{2}=\frac{5}{7}\)
=> \(x:\frac{1}{2}=\frac{11}{15}-\frac{5}{7}=\frac{2}{105}\)
=> \(x=\frac{2}{105}\cdot\frac{1}{2}=\frac{1}{105}\)
d) \(x\cdot\frac{3}{7}+\frac{1}{6}=\frac{17}{18}\)
=> \(x\cdot\frac{3}{7}=\frac{17}{18}-\frac{1}{6}=\frac{7}{9}\)
=> \(x=\frac{7}{9}:\frac{3}{7}=\frac{7}{9}\cdot\frac{7}{3}=\frac{49}{27}\)
Bài 1 :
\(a,\frac{7}{15}+x\times\frac{5}{6}=\frac{2}{3}\)
\(x\times\frac{5}{6}=\frac{2}{3}-\frac{7}{15}\)
\(x\times\frac{5}{6}=\frac{1}{5}\)
\(x=\frac{1}{5}:\frac{5}{6}\)
\(x=\frac{6}{25}\)
\(b,x:\frac{5}{6}-\frac{1}{3}=\frac{7}{12}\)
\(x:\frac{5}{6}=\frac{7}{12}+\frac{1}{3}\)
\(x:\frac{5}{6}=\frac{11}{12}\)
\(x=\frac{11}{12}\times\frac{5}{6}\)
\(x=\frac{55}{72}\)
\(c,\frac{11}{15}-x:\frac{1}{2}=\frac{5}{7}\)
\(x:\frac{1}{2}=\frac{11}{15}-\frac{5}{7}\)
\(x:\frac{1}{2}=\frac{2}{105}\)
\(x=\frac{2}{105}\times\frac{1}{2}\)
\(x=\frac{1}{105}\)
\(d,x\times\frac{3}{7}+\frac{1}{6}=\frac{17}{18}\)
\(x\times\frac{3}{7}=\frac{17}{18}-\frac{1}{6}\)
\(x\times\frac{3}{7}=\frac{7}{9}\)
\(x=\frac{7}{9}:\frac{3}{7}\)
\(x=\frac{49}{27}\)
