Convert to fractions: Step $1$ : Convert decimals to fractions for easier calculation. $\newline$ $0.5 \div 0.1 \times 0.4$ $\newline$ = $(\frac{5}{10}) \div (\frac{1}{10}) \times (\frac{4}{10})$
Perform division first: Step $2$ : Perform the division first, according to order of operations (PEMDAS/BODMAS). $\newline$ = $(\frac{5}{10}) \times (\frac{10}{1}) \times (\frac{4}{10})$ $\newline$ = $5 \times 10 \times 4 / 10 / 10$
Simplify multiplication and division: Step $3$ : Simplify the multiplication and division. $\newline$ = $200 / 10$ $\newline$ = $20$
