Question

У тебя есть девятилитровое ведро и четырёхлитровый бидон . Набери с их помощью 7 литров воды из пруда.

Answer 1

1) Набираем ПОЛНОЕ ведро воды. 9 литров
2) Переливаем с ведра в бидон до полна. 9-4=5литров
3) Сливаем с бидона воду до половины. 4/2=2литра
4) Доливаем в ведро: в итоге в ведре 7 литров воды. 5+2=7

Answer 2

Calculating Water Amounts

To get 7 liters of water using a 9-liter bucket and a 4-liter jug, you can follow these steps:

1. Fill the 9-liter bucket completely. 2. Pour water from the 9-liter bucket into the 4-liter jug. This leaves 5 liters in the 9-liter bucket and fills the 4-liter jug completely. 3. Empty the 4-liter jug. 4. Pour the remaining 5 liters from the 9-liter bucket into the 4-liter jug. 5. Fill the 9-liter bucket again. 6. Carefully pour water from the 9-liter bucket into the 4-liter jug until it's full. This will take 1 liter, leaving 8 liters in the 9-liter bucket.

Now, you have 8 liters of water in the 9-liter bucket and 4 liters in the 4-liter jug, totaling 12 liters. By pouring 4 liters from the 9-liter bucket into the 4-liter jug, you'll be left with 7 liters in the 9-liter bucket and 4 liters in the 4-liter jug.

This method allows you to measure 7 liters of water using the 9-liter bucket and the 4-liter jug.
