Помогите с уравнением пожалуйста

Answer 1

Ответ:

$2 \frac{2}{5} \div x = \frac{48}{75}$

$x = 0$

$2 \frac{2}{5} \div x = \frac{48}{75} .x≠0$

$2 \frac{2}{5} = \frac{2 \times 5 + 2}{5} = \frac{12}{5}$

$x = \frac{1}{x}$

$\frac{48}{75} = \frac{16}{25}$

$\frac{12}{5} \times \frac{1}{x} = \frac{16}{25}$

$\frac{12}{5} \times \frac{1}{x} = \frac{12 \times 1}{5x} = \frac{12}{5x}$

$\frac{12}{5x} = \frac{16}{25}$

$12 \times 25 = 16 \times 5x$

$300 = 80x$

$80x = 300$

|:80

$x = \frac{15}{4} .x≠0$

$x = \frac{15}{4}$
