16 * 3 = 48.

(32 + 38) / 10 = 7.

(36 / 9) * 13 = 52.

12 * б + 8.

Второе слагаемое = 92 - 23 = 69.

(Наибольшее двузначное нечётное число) / 3.

Второй множитель = 70 / 5 = 14.

150 / 3 = 50.

108 * 2 = 216.

72 / 3 = 24.

Дополнение до 1 км: 760 м.

Наибольшее число, которое делится на 7 и меньше 78, это 77.

5 рублей 23 копейки = 523 копейки.

Стоимость покупки = 100 - 53 = 47 рублей.

В двух таких домах всего 72 этажа (36 * 2).

Всего рабочих у фермера: 14 мужчин + 14 * 3 женщины = 14 мужчин + 42 женщины = 56 рабочих.

Стоимость моркови: 4 * 12 = 48 рублей. Стоимость картофеля: 5 * 16 = 80 рублей. Общая стоимость покупки: 48 + 80 = 128 рублей.
