Решение пропорцией:

1540 автомобилей составляет 44% месячного плана, значит месячный план равен 1540 / 0.44 = 3500 автомобилей.

Решение по правилам решения задач на проценты:

Месячный план выражается как 100%, следовательно, известно, что 1540 автомобилей составляет 44/100 * Месячный план = 44/100 * Месячный план = 1540.

Решив уравнение, месячный план = 1540 / 0.44 = 3500 автомобилей.

Пошаговое объяснение:

44% = 44 : 100 = 0,44

1540 : 0,44 = 3500 (автомобилей) - должен выполнить завод по плану

1540 деталей = 44%

х деталей = 100%

1540/х = 44/100

44 * х = 100 * 1540

44х = 154000

х = 154000 : 44

х = 3500

3500 автомобилей должен выполнить завод
