4 Решите пропорцию: 1) x/8 = 12/32 2) 24/x = 1/3 3) 25/4 = 200/x

Решение:

1. $$ \frac{x}{8} = \frac{12}{32} $$

   $$ x = \frac{12 \times 8}{32} = \frac{96}{32} = 3 $$

2. $$ \frac{24}{x} = \frac{1}{3} $$

   $$ x = 24 \times 3 = 72 $$

3. $$ \frac{25}{4} = \frac{200}{x} $$

   $$ x = \frac{200 \times 4}{25} = \frac{800}{25} = 32 $$

Ответ: 1) x = 3; 2) x = 72; 3) x = 32
