Question

З 200 кг картоплі отримують 36 кг крохмалю.Скільки кг крохмалю отримують із 750 кг картоплі? Скільки кг картоплі потрібно, щоб отримати 45 кг крохмалю? варіанти відповідей 125 кг картоплі; 150 кг крохмалю 135 кг крохмалю; 250 кг картоплі 135 кг картоплі; 150 кг крохмалю 125 кг картоплі; 250 кг крохмалю;

Answer 1

Ответ: 135 кг крохмалю; 250 кг картоплі

Пошаговое объяснение:

36/200= 0,18 кг ( с одного кг картошки 0.18 кг крахмала)

750 Х 0.18= 135 кг (с 750 кг картошки получиться 135 кг крахмала)

45 / 0.18 = 250 кг  ( для 45 кг крахмала нужно 250 кг картошки )

Answer 2

Ответ:

Пошаговое объяснение:

Составим пропорцию:

200/750 = 36/х

х = 750*36 / 200

х = 27000/ 200

х = 135

Ответ: 135 кг крахмала из 750 кг картошки

200/х = 36/45

х = 200*45 / 36

х = 9000/36

х = 250

Ответ : 250 кг картошки потребуется для 45 кг крахмала

Answer 3

Calculation of Starch Content in Potatoes

To calculate the amount of starch obtained from a given quantity of potatoes, we can use the ratio of starch content to potato weight.

According to the information provided, 200 kg of potatoes yield 36 kg of starch.

To find out how much starch can be obtained from 750 kg of potatoes, we can set up a proportion:

Proportion 1:

200 kg of potatoes -> 36 kg of starch

750 kg of potatoes -> x kg of starch

Using the proportion, we can solve for x:

x = (750 kg of potatoes * 36 kg of starch) / 200 kg of potatoes

Calculating this, we find that 750 kg of potatoes would yield approximately 135 kg of starch.

Calculation of Potato Quantity for a Desired Starch Amount

To determine the amount of potatoes needed to obtain a specific quantity of starch, we can set up another proportion.

According to the information provided, we want to obtain 45 kg of starch.

Proportion 2:

200 kg of potatoes -> 36 kg of starch

x kg of potatoes -> 45 kg of starch

Using the proportion, we can solve for x:

x = (45 kg of starch * 200 kg of potatoes) / 36 kg of starch

Calculating this, we find that approximately 250 kg of potatoes would be needed to obtain 45 kg of starch.

Therefore, the correct answer is: - To obtain 45 kg of starch, approximately 250 kg of potatoes are needed. - To obtain 135 kg of starch, approximately 750 kg of potatoes are needed.
