Question

если (6x) : (5y) = 12 : 4 то отношение y/x равно

Answer 1

$\frac{6x}{5x} = \frac{12}{4}$
$\frac{x}{y} = \frac{12 \times 5}{6 \times 4} = \frac{5}{2}$

Answer 2

$\frac{6x}{5y} = \frac{12}{4}$
$\frac{6}{5}* \frac{x}{y} = \frac{12}{4}$
$\frac{x}{y} = \frac{12}{4} : \frac{6}{5}$
$\frac{x}{y} = \frac{12*5}{4*6} = \frac{60}{24} = 2,5$
