Answer 4

a) \(\frac{2}{7}\)* X =\(\frac{2}{3}\)=>X=\(\frac{2}{3}\):\(\frac{2}{7}\)=>X=\(\frac{7}{3}\)

b)\(\frac{2}{5}\):X =\(\frac{1}{3}\)=> X=\(\frac{2}{5}\):\(\frac{1}{3}\)=\(\frac{6}{5}\)

c) X :\(\frac{7}{11}\)=22 =>X=22 * \(\frac{7}{11}\)=14

Answer 6

a)\(\frac{2}{7}\)x \(x=\frac{2}{3}\)

               \(x=\frac{2}{3}:\frac{2}{7}=\frac{7}{3}\)

b)\(\frac{2}{5}:x=\frac{1}{3}\)

         \(x=\frac{2}{5}:\frac{1}{3}=\frac{6}{5}\)

c)\(x:\frac{7}{11}=22\)

\(x=22\)x\(\frac{7}{11}=14\)
