Find the reciprocal ratio of (i) \[\mathbf{4}:\text{ }\mathbf{7}\] (ii) \[{{\mathbf{3}}^{\mathbf{2}}}:\text{ }{{\mathbf{4}}^{\mathbf{2}}}\]

(i) \[\mathbf{4}:\text{ }\mathbf{7}\]

We know that

Reciprocal ratio of \[4:\text{ }7\text{ }=\text{ }7:\text{ }4\]

(ii) \[{{\mathbf{3}}^{\mathbf{2}}}:\text{ }{{\mathbf{4}}^{\mathbf{2}}}\]

We know that

Reciprocal ratio of \[{{3}^{2}}:\text{ }{{4}^{2}}~=\text{ }{{4}^{2}}:\text{ }{{3}^{2}}~=\text{ }16:\text{ }9\]
