Question

Из кувшина отлили одну третью молока а потом ещё 0,5 литра после этого в кувшине осталось 3,5 литра молока сколько литров молока было в кувшине первоначально

Answer 1

3,5 + 0,5 = 4 (л) - осталось в кувшине после того, как из него отлили 1/3 молока.
1 - 1/3 = 3/3 - 1/3 = 2/3 - составляют 4 литра молока.
4 : 2 · 3 = 6 (л) - молока было в кувшине первоначально.
Ответ: 6 л.

Answer 2

Calculation of Initial Amount of Milk in the Pitcher

To calculate the initial amount of milk in the pitcher, we need to subtract the amount of milk poured out from the final amount of milk in the pitcher.

Given information: - One-third of the milk was poured out from the pitcher. - After pouring out one-third of the milk, an additional 0.5 liters of milk was poured into the pitcher. - The final amount of milk in the pitcher is 3.5 liters.

Let's calculate the initial amount of milk in the pitcher step by step:

1. Calculate the amount of milk poured out from the pitcher: - One-third of the milk was poured out, which can be represented as 1/3 * x, where x is the initial amount of milk in the pitcher.

2. Calculate the total amount of milk poured into the pitcher: - After pouring out one-third of the milk, an additional 0.5 liters of milk was poured into the pitcher. - So, the total amount of milk poured into the pitcher can be represented as (1/3 * x) + 0.5.

3. Calculate the initial amount of milk in the pitcher: - Subtract the total amount of milk poured into the pitcher from the final amount of milk in the pitcher: - 3.5 - [(1/3 * x) + 0.5] = x

Let's solve this equation to find the initial amount of milk in the pitcher:

3.5 - [(1/3 * x) + 0.5] = x

Simplifying the equation:

3.5 - (1/3 * x) - 0.5 = x

Combining like terms:

3 - (1/3 * x) = x

Multiplying both sides of the equation by 3 to eliminate the fraction:

9 - x = 3x

Adding x to both sides of the equation:

9 = 4x

Dividing both sides of the equation by 4:

x = 9/4

Therefore, the initial amount of milk in the pitcher was 2.25 liters.

Answer:

The initial amount of milk in the pitcher was 2.25 liters.
