Question

помогите решить задачу: в магазин привезли 10 центнеров винограда . до обеда продали 2/8 всего винограда. а после обеда 2/5 остатка. сколько винограда осталось продать?

Answer 1

Переведем:

1 ц=100кг

10 ц=1000 кг

1000*2/8=250 кг продали до обеда

1000-250=750 кг осталось

750*2/5=300 кг после обеда

750-300=450 кг =4,5 тосталось продать

Answer 2

10 центнеров=10000кг

до обеда 10000/8*2=2500 кг

10000-2500=7500кг осталось

7500/5*2=3000 кг

2500+3000=5500 кг продали

10000-5500=4500 кгили 4,5 ц осталось продать

Задача:

В магазин привезли 10 центнеров винограда. До обеда продали 2/8 всего винограда, а после обеда 2/5 остатка. Сколько винограда осталось продать?

Решение:

Давайте посчитаем, сколько винограда было продано до обеда и после обеда, а затем вычислим остаток.

1. Продано до обеда: 2/8 * 10 центнеров = 2.5 центнера. 2. Остаток после обеда: (1 - 2/5) * (10 - 2.5) центнеров = (3/5) * (7.5) центнера.

Теперь сложим количество винограда, проданного до обеда, и остаток после обеда, чтобы найти общее количество винограда, которое осталось продать:

3. Общий остаток винограда: 2.5 центнера + (3/5) * (7.5) центнера = 2.5 + (3/5) * (7.5) центнера.

Теперь мы можем вычислить общий остаток винограда:

4. Общий остаток винограда: 2.5 + (3/5) * (7.5) центнера = 2.5 + (3/5) * 7.5 центнера.

Давайте вычислим это:

2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/5) * 7.5 = 2.5 + (3/
