Question

Объём бидона равен 4 л, что составляет 2/7 объёма канистры и 2 % объёма бочки. Сколько канистр можно налить из бочки до краёв наполненной жидкостью ? Сколько жидкости ёщё останется ?

Answer 1

4*7/2=14л объем канистры,

4*100/2=200л объем бочки,

а)200-(14+4)=182л больше жидкости вмещает бочка,

б)200:4=50 раз объем бочки больше объема бидона,

в)200:14=14(ост4)  14 канистр, и 4 литра жидкости останется.

Answer 2

Problem Analysis

We are given that the volume of a canister is 2/7 of the volume of a barrel and 2% of the volume of a bucket. The volume of the barrel is 4 liters. We need to determine how many canisters can be filled from the barrel and how much liquid will be left.

Solution

Let's start by finding the volume of the canister. We are given that the volume of the canister is 2/7 of the volume of the barrel and 2% of the volume of the bucket.

Given: - Volume of the barrel = 4 liters

To find the volume of the canister, we can use the following equation:

Volume of the canister = (2/7) * Volume of the barrel

Substituting the given values, we have:

Volume of the canister = (2/7) * 4 liters

Simplifying the equation, we get:

Volume of the canister = (8/7) liters

So, the volume of the canister is 8/7 liters.

Next, we need to determine how many canisters can be filled from the barrel. To do this, we divide the volume of the barrel by the volume of the canister:

Number of canisters = Volume of the barrel / Volume of the canister

Substituting the given values, we have:

Number of canisters = 4 liters / (8/7) liters

Simplifying the equation, we get:

Number of canisters = 4 * (7/8)

Number of canisters = 3.5

Since we cannot have a fraction of a canister, we can conclude that we can fill 3 canisters from the barrel.

Finally, we need to determine how much liquid will be left in the barrel. To do this, we subtract the total volume of the filled canisters from the volume of the barrel:

Remaining liquid in the barrel = Volume of the barrel - (Volume of the canister * Number of canisters)

Substituting the given values, we have:

Remaining liquid in the barrel = 4 liters - (8/7 liters * 3 canisters)

Simplifying the equation, we get:

Remaining liquid in the barrel = 4 liters - (24/7 liters)

Remaining liquid in the barrel = (28/7 liters) - (24/7 liters)

Remaining liquid in the barrel = 4/7 liters

So, there will be 4/7 liters of liquid remaining in the barrel.

Answer

Based on the given information, we can fill 3 canisters from the barrel, and there will be 4/7 liters of liquid remaining in the barrel.
