Question

Tính :

 \(a.\frac{1}{6}\times x=\frac{1}{9}\)

\(b.\frac{15}{16}:x=\frac{5}{6}\)

Answer 1

a) \(\frac{1}{6}\) \(\times\)\(x\)= \(\frac{1}{9}\)

                     \(x\)= \(\frac{1}{9}\) \(:\) \(\frac{1}{6}\)

                     \(x\)= \(\frac{2}{3}\)

b) \(\frac{15}{16}\) \(:\) \(x\) = \(\frac{5}{6}\)

                     \(x\)= \(\frac{15}{16}\)\(:\) \(\frac{5}{6}\)

                     \(x\)= \(\frac{9}{8}\)

Answer 2

a. \(\frac{1}{6}\times x=\frac{1}{9}\)

\(x=\frac{1}{9}\div\frac{1}{6}\)

\(x=\frac{2}{3}\)

b. \(\frac{15}{16}\div x=\frac{5}{6}\)

\(x=\frac{15}{16}\div\frac{5}{6}\)

\(x=\frac{9}{8}\)

Answer 3

a. \(\frac{1}{6}\times x=\frac{1}{9}\)

               \(x=\frac{1}{9}:\frac{1}{6}\)

               \(x=\frac{1}{9}x\frac{6}{1}\)

                \(x=\frac{2}{3}\)

b.\(\frac{15}{16}:x=\frac{5}{6}\)

           \(x=\frac{15}{16}:\frac{5}{6}\)  

           \(x=\frac{15}{16}\times\frac{6}{5}\)

           \(x=\frac{9}{8}\)

Answer 4

\(a.x=\frac{1}{9}:\frac{1}{6}\)

\(x=\frac{2}{3}\)

\(b.x=\frac{15}{16}:\frac{5}{6}\)

\(x=\frac{9}{8}\)

Answer 5

a )

\(\frac{1}{6}\times x=\frac{1}{9}\)

           \(x=\frac{1}{9}\div\frac{1}{6}\)

           \(x=\frac{2}{3}\)

b ) 

\(\frac{15}{16}\div x=\frac{5}{6}\)

             \(x=\frac{15}{16}\div\frac{5}{6}\)

             \(x=\frac{9}{8}\)

Answer 6

a )

\(\frac{1}{6}\times x=\frac{1}{9}\)

           \(x=\frac{1}{9}\div\frac{1}{6}\)

           \(x=\frac{2}{3}\)

b )

\(\frac{15}{16}\div x=\frac{5}{6}\)

             \(x=\frac{15}{16}\div\frac{5}{6}\)

             \(x=\frac{9}{8}\)
