ответ: Для решения этой задачи нам нужно знать, что символ "<" означает "меньше"

Ответ: а) m < n; б) m < n.

Пошаговое объяснение: Сначала мы знаем, что символ "<" означает "меньше".

Для каждой задачи дано неравенство, которое содержит две переменные, m и n, умноженные на какое-то число или дробь.

В задаче (а) неравенство выглядит как 0,12m < 0,12n. Обе части неравенства можно разделить на 0,12, и получим m < n. Это верно, потому что если мы делим обе части на положительное число, то неравенство сохраняет свой знак, и если m было меньше, чем n до деления, то оно останется меньше после деления на положительное число.

В задаче (б) неравенство выглядит как 7,3m < 7,3n. Обе части можно разделить на 7,3, и получим m < n. Это также верно по той же причине, что мы можем делить обе части неравенства на положительное число, и неравенство сохранит свой знак.

Ответ для обеих задач: m < n.

recorded system was in Ancient Greece in 600BC. Since then, rail-links were built to connect
short distances. In the early 19th century, the first passengers travelled on the railways with
horse-drawn carriages.
Air-travel is the most modern form of public transport and it was developed in the 20th century.
