Question

Из 150 кг картофеля получают 27 кг крахмала.Сколько килограммов крахмала получат из 420 кг картофеля?Сколько килограммов картофеля необходимо,чтобы получить 30,6 кг крахмала?

Answer 1

420/150=2.8отсюда 2.8*27=75.6кг
а 2 вопрос ?

Answer 2

Calculation 1: How many kilograms of starch will be obtained from 420 kg of potatoes?

To calculate the amount of starch obtained from 420 kg of potatoes, we can use the given information that 150 kg of potatoes yield 27 kg of starch.

Let's set up a proportion to solve for the unknown amount of starch:

150 kg of potatoes is to 27 kg of starch as 420 kg of potatoes is to x kg of starch.

Using the proportion, we can solve for x:

(150 kg / 27 kg) = (420 kg / x kg)

Cross-multiplying, we get:

150 kg * x kg = 27 kg * 420 kg

Simplifying the equation:

x kg = (27 kg * 420 kg) / 150 kg

Calculating the result:

x kg = 75.6 kg

Therefore, from 420 kg of potatoes, 75.6 kg of starch will be obtained.

Calculation 2: How many kilograms of potatoes are needed to obtain 30.6 kg of starch?

To calculate the amount of potatoes needed to obtain 30.6 kg of starch, we can use the given information that 150 kg of potatoes yield 27 kg of starch.

Let's set up a proportion to solve for the unknown amount of potatoes:

150 kg of potatoes is to 27 kg of starch as x kg of potatoes is to 30.6 kg of starch.

Using the proportion, we can solve for x:

(150 kg / 27 kg) = (x kg / 30.6 kg)

Cross-multiplying, we get:

150 kg * 30.6 kg = 27 kg * x kg

Simplifying the equation:

x kg = (150 kg * 30.6 kg) / 27 kg

Calculating the result:

x kg = 170 kg

Therefore, to obtain 30.6 kg of starch, approximately 170 kg of potatoes will be needed.
