Пошаговое объяснение:

Сначала мы умножаем числители дробей между собой: 1*3=3

Затем мы умножаем знаменатели дробей между собой: 9*5=45

Результат умножения дробей равна \frac{1}{9}* \frac{3}{5} = \frac{3}{45}.

Но мы можем упростить эту дробь поделив числитель и знаменатель на их общий делитель в данном случае равен 3.

Поэтому \frac{3}{45}упрощается до \frac{1}{15}.

\frac{1}{9}*\frac{3}{5}=\frac{1}{15}
