x кг — 100 %;
16,4 кг — 82 %.
x/16.4 = 100/82;
x = (16.4 * 100)/82 = 1640/82 = 20 кг вишни надо взять.
Пошаговое объяснение:
Из условия известно, что при изготовлении пюре из вишни 18 % идёт в отходы. Для того, чтобы найти сколько надо взять вишен, чтобы получить 16,4 кг пюре составим и решим пропорцию.
Давайте обозначим с переменной x кг вес вишни, которую нужно взять для приготовления пюре и примем ее за 100 %.
Давайте найдем сколько в процентах составляет вес пюре от веса вишен:
100 % - 18 % = 82 %.
Остается составить и решить пропорцию.
