2 и 2/5 - это правильная дробь, переведем в неправильную:

2 и 2/5 = (2 * 5) / 5 + 2/5 = 10/5 + 2/5 = 12/5.

Также переведем 3,2 с десятичной в неправильную дробь:

3,2 = 32/10.

Чтобы найти отношения 32/10 к 12/5, поделим первое на второе:

32/10 : 12/5, переворачиваем вторую дробь и умножаем.

32/10 * 5/12 = 32/12 * 5/10 = 8/3 * 1/2 = 8/6 = 4/3 = 1 и 1/3.

Ответ: 3,2 относится к (2 и 2/5), как 4 к 3.
