Answer 1

$$\begin{gathered} \left(\mathrm{a}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{m}=1000\mathrm{mm} \\ \mathrm{Now},247\mathrm{mm}=\frac{247}{1000}\mathrm{m}=0.247\mathrm{m} \\ \left(\mathrm{b}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{kg}=100\mathrm{dag} \\ \mathrm{Now},416\mathrm{dag}=\frac{416}{100}\mathrm{kg}=4.16\mathrm{kg} \\ \left(\mathrm{c}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{kl}=1000\mathrm{l} \\ \mathrm{Now},3042\mathrm{l}=\frac{3042}{1000}\mathrm{kl}=3.042\mathrm{kl} \\ \left(\mathrm{d}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{km}=100000\mathrm{cm} \\ \mathrm{Now},121\mathrm{cm}=\frac{121}{100000}=0.00121\mathrm{km} \\ \left(\mathrm{e}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{gram}=100\mathrm{cg} \\ \mathrm{Now},3552\mathrm{cg}=\frac{3552}{100}\mathrm{g}=35.52\mathrm{g} \\ \left(\mathrm{f}\right). \\ \mathrm{We}\mathrm{know}\mathrm{that}, \\ 1\mathrm{hg}=100\mathrm{g} \\ \mathrm{Now},1248\mathrm{g}=\frac{1248}{100}\mathrm{hg}=12.48\mathrm{hg} \end{gathered}$$
