Answer 1

Ответ:

$x \div 4.5 = \frac{16}{5} \div \frac{9}{4} \: \: \: \: \: x = \frac{16}{5} \times \frac{4}{9} \times \frac{9}{2} \: \: \: x = \frac{16}{5} \times \frac{2}{1} \times \frac{1}{1} \: \: \: x = \frac{32}{5} = 6 \frac{2}{5} \\ 7y = 4.5 \times 21 \div 27 \: \: 7y = 3.5\: \: y = 0.5 \\ y + 2 = 1.25 \times 2.4 \div 0.6 \: \: y + 2 = 5 \: \: y = 5 - 2 \: \: y = 3$
