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

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