Question

Помогите пожалуйста решить пример

Answer 1

$\frac{(5.7 \div 0.3 - 8 \frac{1}{3}) \times 0.75 }{(2 \frac{1}{8} + 1.75) \div 15.5} = \frac{8}{ \frac{1}{4} } = 32 \\ \\ 1) \: \: \: 5.7 \div 0.3 = \frac{57}{3} = 19 \\ 2) \: \: \: 19 - 8 \frac{1}{3} = 18 - 8 + \frac{3 - 1}{3} = 10 \frac{2}{3} \\ 3) \: \: \: 10 \frac{2}{3} \times 0.75 = \frac{32}{3} \times \frac{75}{100} = \frac{32 \times 3}{3 \times 4} = 8 \\ 4) \: \: \: 2 \frac{1}{8} + 1.75 = 2 \frac{1}{8} + 1 \frac{75}{100} = 2 \frac{1}{8} + 1 \frac{3}{4} = 2 \frac{1}{8} + 1 \frac{6}{8} = 3 \frac{7}{8} \\ 5) \: \: \: 3 \frac{7}{8} \div 15.5 = \frac{31}{8} \div \frac{155}{10} = \frac{31}{8} \div \frac{31}{2} = \frac{31 \times 2}{8 \times 31} = \frac{1}{4} = 0.25 \\ 6) \: \: \: 8 \div \frac{1}{4} = 8 \times 4 = 32$
