Answer 1

$0.325 = \frac{13}{40 } \\ 1) \frac{17}{40} - \frac{13}{40} = \frac{4}{40} = \frac{1}{10} \\ 2) \frac{1}{10} \div \frac{1}{5} = \frac{1 \times 5}{10 \times 1} = \frac{5}{10} = \frac{1}{2} \\ 3) \frac{1}{2} \times 0.4 = \frac{1}{2} \times \frac{4}{10} = \frac{4}{20} = \frac{1}{5} \\ 4) \frac{1}{5} \times 2 = 0.2 \times 2 = 0.4$
