10.2
21 ÷ 0.2
30.‾2
4(0.2)²

Answer:- 1

Explanation:-

Solution:

\begin{aligned} 1 \div 0.2 = \frac{1}{0.2} = \frac{10}{2} = 5; \\ 0. \bar{2} = 0.222...; \\ {(0.2)}^{2} = 0.04 \\ 0.04 < 0.2 < 0.22.... < 5 \\ Since 0.04 is the least, so {(0.2)}^{2} is the least . \end{aligned}

$\eqalign{ & 1 \div 0.2 = \frac{1}{{0.2}} = \frac{{10}}{2} = 5; \cr & 0.\overline 2 = 0.222...; \cr & {\left( {0.2} \right)^2} = 0.04 \cr & 0.04 < 0.2 < 0.22.... < 5 \cr & {\text{Since}}\,0.04\,{\text{is}}\,{\text{the}}\,{\text{least,}}\,{\text{so}}\,{\left( {0.2} \right)^2}\,{\text{is}}\,{\text{the}}\,{\text{least}}. \cr}$
