Найдем доли первого и третьего участка = 1/10 + 7/60 = 6/60 + 7/60 = 13/60 или это 100- 48 = 52% площади всех участков . На 1 долю приходится 52 / 13 = 4 % Значит третий участок равен 4 * 7 = 28%
Разность в процентах второго и третьего участка равна = 48 - 28 = 20% или 2,5 га . Отсюда площадь всех участков равна = 2,5/20 * 100 = 12,5 га
Площадь первого участка = 12,5 * 48 /100 = 6 га
Площадь первого и третьего участка = 12,5 - 6 = 6,5 из них первого 6,5/13 * 6 = 3,0 га , третьего = 6,5 / 13 * 7 = 3,5 га
