4 день
вечером 4го дня осталось 2 конфеты.
значит утром должно было быть 4 конфеты, т.к. утром надо съесть 2 конфеты. занесем это в таблицу.
3 день
Эти четыре конфеты утра 4го дня - это 2/3 от того, что было вечером зго дня. (потому, что 1/3 она съела). значит вечером Зго дня было
4:(2/3) = 6. а утром значит было (6+2) =8 конфет. -- занесем в таблицу.
2 день
аналогично Зму дню:
вечер
8:(2/3)= 12
утро
12+2 = 14
вечер
1 день
14:(2/3) = 21
Значит днем 1го дня была 21 конфета столько подарила бабушка Ане.
