Answer 2

Calculating the Amount of Dried Mushrooms

To calculate the amount of dried mushrooms that can be obtained from 0.5 centners (50 kg) of fresh mushrooms, we can use the given information that the mass of dried mushrooms is 14% of the mass of fresh mushrooms.

Step 1: Calculate the amount of dried mushrooms that can be obtained from 0.5 centners (50 kg) of fresh mushrooms. - 14% of 50 kg = 0.14 * 50 = 7 kg.

So, 7 kg of dried mushrooms can be obtained from 0.5 centners (50 kg) of fresh mushrooms.

Calculating the Amount of Fresh Mushrooms Needed

To calculate the amount of fresh mushrooms needed to obtain 2.8 kg of dried mushrooms, we can use the given information that the mass of dried mushrooms is 14% of the mass of fresh mushrooms.

Step 2: Calculate the amount of fresh mushrooms needed to obtain 2.8 kg of dried mushrooms. - Let x be the mass of fresh mushrooms needed to obtain 2.8 kg of dried mushrooms. - We can set up the equation: 14% of x = 2.8 kg. - Solving for x: 0.14x = 2.8. - x = 2.8 / 0.14 = 20 kg.

So, 20 kg of fresh mushrooms are needed to obtain 2.8 kg of dried mushrooms.

Therefore, to obtain 7 kg of dried mushrooms, 0.5 centners (50 kg) of fresh mushrooms are needed, and to obtain 2.8 kg of dried mushrooms, 20 kg of fresh mushrooms are needed.
