Question

Из 20 литров бидона, наполненного водой, отлили 8 л. Какую часть бидона заполняет оставшаяся в нём вода? Во сколько раз воды в полном бидоне было больше, чем осталось?

Answer 1

1)20-8=12(л)-осталось воды
2) 12:20=0,6(части) бидона заполняет оставшаяся в нем вода
3)20:12=1,66(раз) -во столько раз воды в полном бидоне было больше, чем осталось

Answer 2

Problem Analysis

We have a container filled with 20 liters of water. We pour out 8 liters of water from the container. We need to determine the fraction of the container that is still filled with water and the ratio of the remaining water to the original amount.

Solution

To find the fraction of the container that is still filled with water, we need to calculate the ratio of the remaining water to the original amount of water in the container.

Let's calculate the fraction of the container that is still filled with water:

1. Calculate the remaining amount of water in the container: 20 liters - 8 liters = 12 liters.

2. Calculate the fraction of the container that is still filled with water: remaining water / original amount of water = 12 liters / 20 liters.

Answer: The remaining water fills 12/20 or 3/5 of the container.

To find the ratio of the remaining water to the original amount, we need to calculate the difference between the original amount of water and the remaining amount of water.

Let's calculate the ratio of the remaining water to the original amount:

1. Calculate the difference between the original amount of water and the remaining amount of water: 20 liters - 12 liters = 8 liters.

2. Calculate the ratio of the remaining water to the original amount: remaining water / original amount of water = 8 liters / 20 liters.

Answer: The remaining water is 8/20 or 2/5 of the original amount.

Conclusion

After pouring out 8 liters of water from a 20-liter container, the remaining water fills 3/5 of the container, and the remaining water is 2/5 of the original amount.
