Картофель содержит 20℅крахмала а овес 60℅. Сколько надо взять картофеля что бы в нем содержалось столько же крахмала сколько его содержиться в 2 кг овса? Пж спасибо заранее

Answer 1

р- нужное кол-во картофеля ,значит
р×0,2=2 кг× 0,6
р=2 кг × 0,6 : 0,2
р=2 кг × 3
р= 6 кг значит нужно 6 кг картофеля

Answer 2

Calculating the Amount of Potatoes Needed

To calculate the amount of potatoes needed to contain the same amount of starch as 2 kg of oats, we can use the given information that potatoes contain 20% starch and oats contain 60% starch.

Step 1: Calculate the Starch Content in 2 kg of Oats

First, let's calculate the amount of starch in 2 kg of oats: - 60% of 2 kg = 60/100 * 2 kg = 1.2 kg of starch in 2 kg of oats.

Step 2: Calculate the Amount of Potatoes Needed

Now, we need to find out how much potatoes are needed to contain the same amount of starch as 2 kg of oats.

Let's assume x kg of potatoes are needed.

The starch content in x kg of potatoes can be calculated as: - 20% of x kg = 20/100 * x kg = 0.2x kg of starch in x kg of potatoes.

Step 3: Equating the Starch Content

We want the amount of starch in x kg of potatoes to be equal to the amount of starch in 2 kg of oats: - 0.2x kg = 1.2 kg - x = 1.2 kg / 0.2 - x = 6 kg

Answer: To contain the same amount of starch as 2 kg of oats, you would need 6 kg of potatoes.
