3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{lb}& =\frac{0.45359237\cancel{\mathrm{kg}}}{0.001\cancel{\mathrm{kg}}}\times 1\mathrm{g}\\ & =\frac{0.45359237}{0.001}\mathrm{g}\\ & =453.59237\mathrm{g}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{g}& =\frac{0.001\cancel{\mathrm{kg}}}{0.45359237\cancel{\mathrm{kg}}}\times 1\mathrm{lb}\\ & =\frac{0.001}{0.45359237}\mathrm{lb}\\ & =0.002204622622\mathrm{lb}\end{array}$$
