80: 16 = 5 (Как найти значение частного 80 и 16? Делитель 16 надо умножить на такое однозначное число, чтобы получилось делимое 80. Начинаем подбирать. 16 · 2 = 36 – не подходит. 16 · 3 = 48 – не подходит. 16 · 4 = 64 – не подходит. 16 · 5 = 80 – подходит. Значит, 80: 16 = 5). (Или по – другому. Если в числе 16на конце стоит число 6, то вспоминаем таблицу умножения на 6. На какое число надо умножить 6, чтобы на конце стоял 0. Это 5. Проверяем: 16 · 5 = 80, значит число 5 нам подходит. )
