Ответ: человек потерял 36% крови

Объяснение:

количество крови у 80кг человека равно:

80×0,07=

5,6л

если он потерял 2 л, это в процентах равно:

2×100%:5,6≈35,7≈36%

❗Потеря 1-2 литров крови смертельно опасна для человека!❗

Задача поставлена не очень корректно. Два врача решить не могли...

80 кг = 100%

x кг = 7%

5.6 кг крови - это приблизительно 5.33 л (т.к. плотность крови примерно 1.05 кг/м³, вычисляем по формуле V = m/p)

5.33 л = 100%

2 л = x%

Таким образом, предполагаемый уровень кровопотери в процентах равен приблизительно 37.5%.
