Рабочий потратил 12 м 50 см кабеля. Сколько кабеля осталось в катушке, если всего в ней было 30 м?

1 м = 100 см

30 м = 30 * 100 = 3 000 см

12 м 50 см = 12 * 100 + 50 = 1 200 + 50 = 1 250 см

=============================================

3 000 - 1 250 = 1 750 см = 17 м 50 см

Ответ: в катушке осталось 17 м 50 см.
