Question

2 3/4*4+5 1/6:1/2-10 5/9
срочно помогите пожалуйста

Answer 1

Ответ:

$2 \frac{3}{4} \times 4 + 5 \frac{1}{6} \div \frac{1}{2} - 10 \frac{5}{9} \\ \frac{11}{4} \times \frac{4}{1} + \frac{31}{6} \times \frac{2}{1} - 10 \frac{5}{9} \\ 11 + \frac{31}{3} - \frac{95}{9} \\ \frac{99 + 31 \times 3 - 95}{9} = \frac{97}{9} = 10 \frac{7}{9}$

Или

2.75*4+5 1/6 : 3/6 - 10 5/9 = 11 + 31/3 - 10 5/9 = 11 + 10 3/9 - 10 5/9 = 11 - 2/9 = 10 7/9
