Question

16. Із 600 кг макулатури отримують 156 кг паперу. Скільки кілограмів паперу отримають з 550 кг макулатури? Скіль- кілограмів макулатури потрібно, щоб отримати 91 кг ки от паперу?

Answer 1

Ответ:

Все очень и очень просто.

Пошаговое объяснение:

1)600-156=444

2)444×550=244200

3)244200:91=2683

Answer 2

To find out how many kilograms of paper will be obtained from 550 kg of waste paper, we can use a proportion based on the given information.

Let's set up the proportion using the given values: - From 600 kg of waste paper, 156 kg of paper is obtained. - We want to find out how many kilograms of paper will be obtained from 550 kg of waste paper.

Using the proportion, we can set it up as follows:

600 kg of waste paper / 156 kg of paper = 550 kg of waste paper / x kg of paper

To solve for x, we can cross-multiply and divide:

600 kg of waste paper * x kg of paper = 156 kg of paper * 550 kg of waste paper

x kg of paper = (156 kg of paper * 550 kg of waste paper) / 600 kg of waste paper

Now we can calculate the value of x:

x kg of paper = (156 kg * 550 kg) / 600 kg

Calculating this expression, we find that x is approximately 143 kg of paper.

Therefore, from 550 kg of waste paper, approximately 143 kg of paper will be obtained.

Now let's move on to the second question.

To find out how many kilograms of waste paper are needed to obtain 91 kg of paper, we can again set up a proportion based on the given information.

Let's set up the proportion using the given values: - From 600 kg of waste paper, 156 kg of paper is obtained. - We want to find out how many kilograms of waste paper are needed to obtain 91 kg of paper.

Using the proportion, we can set it up as follows:

600 kg of waste paper / 156 kg of paper = x kg of waste paper / 91 kg of paper

To solve for x, we can cross-multiply and divide:

600 kg of waste paper * 91 kg of paper = 156 kg of paper * x kg of waste paper

x kg of waste paper = (600 kg of waste paper * 91 kg of paper) / 156 kg of paper

Now we can calculate the value of x:

x kg of waste paper = (600 kg * 91 kg) / 156 kg

Calculating this expression, we find that x is approximately 349 kg of waste paper.

Therefore, approximately 349 kg of waste paper is needed to obtain 91 kg of paper.

I hope this helps! Let me know if you have any further questions.
