Question

Помогите пожалуйста срочно ​

Answer 1

$= \frac{ \frac{15}{3} - \frac{15}{5} }{ \frac{2 \times 15}{3} } = \frac{5 - 3 }{ \frac{30}{3} } = \frac{2}{10} = \frac{1}{5} = 0.2$

$= \frac{ \frac{6 \times 2}{3} + \frac{6}{2} }{ \frac{5 \times 6}{6} } = \frac{4 + 3}{5} = \frac{7}{5} = 1 \frac{2}{5} = 1.4$

$= \frac{ \frac{3 \times 10}{10} }{ \frac{4 \times 10}{5} - \frac{10}{2} } = \frac{3}{8 - 5} = \frac{3}{3} = 1$

$= \frac{ \frac{12}{6} }{ \frac{5 \times 12}{6} + \frac{12}{2} } = \frac{2}{10 + 6} = \frac{2}{16} = \frac{1}{8} = 0.125$
