Пошаговое объяснение:

1% = 1 : 100 = 0,01

Если 1% составляет 5 мм

1) 5 : 0,01 = 500 мм

Если 1% составляет 14 м²

2) 14 : 0,01 = 1400 м²

Если 1% составляет 49,5 т

3) 49,5 : 0,01 = 4950 т

Если 1% составляет 3900 книг

4) 3900 : 0,01 = 390000 книг

Если 1% составляет 7,3 кг

5) 7,3 : 0,01 = 730 кг

Если 1% составляет 1 га

6) 1 : 0,01 = 100 га

Если 1% составляет 45 см²

4) 45 : 0,01 = 4500 см²
