Question

2:3/5+3/5:2+1 1/2:6+6:1 1/2=​

Answer 1

Пошаговое объяснение:

$\\ \\ 2 \div \frac{3}{5} + \frac{3}{5} \div 2 + 1 \frac{1}{2} \div 6 + 6 \div 1 \frac{1}{2} = \\ \\ = 2 \times \frac{5}{3} + \frac{3}{5} \times \frac{1}{2} + \frac{3}{2} \times \frac{1}{6} + 6 \div \frac{3}{2} = \\ \\ = \frac{10}{3} + \frac{3}{10 } + \frac{3}{12} + 6 \times \frac{2}{3} = \\ \\ = \frac{10}{3} + \frac{3}{10} + \frac{1}{4} + \frac{12}{3} = \\ \\ = \frac{10}{3} + \frac{3}{10} + \frac{1}{4} + 4 = \\ \\ = \frac{10 \times 20 + 3 \times 6 + 1 \times 15 + 4 \times 60}{60} = \\ \\ = \frac{200 + 18 + 15 + 240}{60} = \frac{473}{60} = 7 \frac{53}{60}$
