Весь виноград примем за единицу (целое)
1-й день 2/5 всего винограда
2-й день 8/25 всего винограда
3-й день - ?
Всего за 3 дня - 50 кг
а) 2/5 = 10/25 - доп.множ. 5 2/5 > 8/25, так как 10/25 > 8/25
ответ: в первый день продано больше.
б) 2/5 + 8/25 = 10/25 + 8/25 = 18/25 ответ: 18/25 винограда продано за первые два дня.
в) 1 - 18/25 = 25/25 - 18/25 = 7/25 - часть винограда, проданная в третий день;
7/25 * 50 = 50 : 25 * 7 = 14 кг винограда продано в третий день. ответ: 14 кг.
г) 50 : 3 = 50 * 1/3 = 50/3 = 16 целых 2/3 кг - столько винограда надо продавать в каждый из трёх дней, чтобы было поровну. ответ: 16 целых 2/3 кг.
