3 целых 1/3- 1 целая 1/3×( 2 целых 3/4÷ 2- 3/4)

решите

Answer 1

$3 \frac{1}{3} - 1 \frac{1}{3} \times (2 \frac{3}{4} \div 2 - \frac{3}{4} ) = \frac{3}{10} - \frac{4}{3} \times ( \frac{11}{4} \div 2 - \frac{3}{4} ) = \frac{3}{10} - \frac{4}{3} \times ( \frac{11}{4 \times 2} - \frac{3}{4} ) = \frac{3}{10} - \frac{4}{3} \times ( \frac{11}{8} - \frac{3}{4} ) = \frac{3}{10} - \frac{4}{3} \times ( \frac{11 - 6}{8} ) = \frac{3}{10} - \frac{4}{3} \times \frac{5}{6} = \frac{3}{10} - \frac{4 \times 5} {3 \times 6} = \frac{10}{3} - \frac{5}{6} = \frac{20 - 5}{6} = \frac{15}{6} = \frac{5}{2} = 2 \frac{1}{2}$
