Задача: Три грибника собрали соответственно 6, 4 и 2 кг грибов и получили за них 6000 рублей прибыли. Как они должны разделить эту прибыль?

Решение: Обычно распределение прибыли соответствует внесённым долям. Грибы, собранные первым и вторым грибником, относятся как 6 к 4, а вторым и третьим — как 4 к 2. В таких случаях вместо двух отношений 6:4 и 4:2 записывается одно отношение 6:4:2, именно в таком отношении и должна быть распределена прибыль.

Следовательно, данная задача очень похожа на задачу на части. Всего имеем

6 + 4 + 2 = 12 частей.

Значит, на каждую часть приходится

6000 : 12 = 500 рублей.

Следовательно, первый грибник должен получить 500 · 6 = 3000 р., второй 500 · 4 = 2000 р., а третий 500 · 2 = 1000 р.
