Answer 2

Ответ:

$\frac{0.3}{0.6} = \frac{0.3 \times 10}{0.6 \times 10} = \frac{3}{6} = \frac{1}{2} = 0.5$

$\frac{3.2}{3} = 3 \frac{2}{10} \div 3 = \frac{32}{13} \times \frac{1}{3} = \frac{32}{39}$

$\frac{0.7}{2.1} = \frac{0.7 \times 10}{2.1 \times 10} = \frac{7}{21} = \frac{1}{3}$

$\frac{2}{2.6} = \frac{1}{1.3} = 1 \div 1 \frac{3}{10} = 1 \div \frac{13}{10} = \frac{10}{13}$

$\frac{0.6}{2.4} = \frac{1}{4}$

$\frac{0.7}{3.5} = \frac{1}{5} = 0.2$

$\frac{6}{1.5} = 6 \div 1 \frac{5}{10} = 6 \div \frac{15}{10} = 6 \times \frac{2}{3} = 2 \times 2 = 4$
