помогите пожалуйста ​

Answer 1

Ответ:

$3 \frac{12}{36} \times ( \frac{3}{5} - \frac{3}{12} ) - 3 \div 1 \frac{1}{2} \\ 1) \: \: \: \: \frac{3}{5 } - \frac{3}{12} = \frac{36 - 15}{60} = \frac{21}{60} = \frac{7}{20} \\ 2) \: \: \: \: 3 \frac{12}{36} \times \frac{7}{20} = \frac{120}{36} \times \frac{7}{20} = \frac{42}{36} = \frac{7}{6} = 1 \frac{1}{6} \\ 3) \: \: \: \: \: 3 \div 1 \frac{1}{2} = 3 \div \frac{3}{2} = \frac{3 \times 2}{1 \times 3} = \frac{2}{1} = 2 \\ 4) \: \: \: \: \: \: 1 \frac{1}{6} - 2 = 1 \frac{1}{6} - 1 \frac{6}{6} = \frac{ - 5}{6}$
