Question

5/6 :3 1/2=; 10 2/3*6.3=;2 3/20*4.2=​

Answer 1

Ответ:

$\frac{5}{6} \div 3 \frac{1}{2} = \frac{5}{6} \div \frac{7}{2} = \frac{5 \times 2}{6 \times 7} = \frac{5}{21} \\ \\ 10 \frac{2}{3} \times 6.3 = \frac{32 \times 63}{3 \times 10} = \frac{16 \times 21}{5} = \frac{336}{5} = \frac{672}{10} = 67.2 \\ \\ 2 \frac{3}{20} \times 4.2 = \frac{43 \times 42}{20 \times 10} = \frac{43 \times 21}{10 \times 10} = \frac{903}{100} = 9.03$
