Question

помогите пожалуйста срочно

Answer 1

$1 \times 7 = 7 \\ 120 \times 10 = 1200 \\ \frac{3 \times 14}{7 \times 9} = \frac{2}{3} \\ \frac{7 \times 4}{8 \times 3} = \frac{7}{2 \times 3} = \frac{7}{6}$
$\frac{12 \times 7}{1 \times 5} = \frac{84}{5} = 16 \frac{4}{5} \\ \frac{10 \times 1}{11 \times 5} = \frac{2}{11} \\ \frac{1 \times 1}{200 \times 200} = \frac{1}{40000} \\ \frac{84 \times 110}{121 \times 63} = \frac{12 \times 10}{11 \times 9} = \frac{4 \times 10}{11 \times 3} = \frac{40}{33} = 1 \frac{7}{40}$
