Пошаговое объяснение:

[tex]2 \frac{1}{2} \div \frac{5}{6} \times \frac{2}{3} \times \frac{1}{2} = 1[/tex]

[tex]1)2 \frac{1}{2} \div \frac{5}{6} = \frac{5}{2} \div \frac{5}{6} = \frac{5 \times 6}{2 \times 5} = \frac{30}{10} = 3[/tex]

[tex]2)3 \times \frac{2}{3} = \frac{6}{3} = \frac{2 \times 3}{1 \times 3} = 2[/tex]

[tex]3)2 \times \frac{1}{2} = \frac{2}{2} = \frac{1 \times 2}{1 \times 2} = 1[/tex]
