Question

После сушки груш остаётся 15 % их первоначальной массы. Какова была масса груш до сушки, если высушенных вышло 3,6 т? Какова масса высушенных груш, если масса до сушки была 5,3 т?

Answer 1

Ответ:

3.6т = 15%, x=100%

x=100×3.6/15= 360/15= 24 т до сушки

5.3т=100% , x=15%

x= 5.3 × 15 / 100 = 79.5 / 100 = 0.795 т после сушки

Answer 2

Ответ:

Пошаговое объяснение:

15% -3,6

100% - х

Х=3,6÷15×100=24т свежих

100% - 5,3

15% - х

5,3×15÷100=0,795т или 795кг

Answer 3

Calculation of the Initial Mass of Pears

To calculate the initial mass of pears before drying, we can use the information provided: after drying, 15% of the original mass remains, and the mass of the dried pears is 3.6 tons.

Let's denote the initial mass of the pears as M.

According to the given information, after drying, 15% of the original mass remains. This can be expressed as:

0.15M = 3.6 tons

To find the initial mass M, we can divide both sides of the equation by 0.15:

M = 3.6 tons / 0.15

Calculating this, we find:

M = 24 tons

Therefore, the initial mass of the pears before drying was 24 tons.

Calculation of the Mass of Dried Pears

Now, let's calculate the mass of the dried pears when the initial mass before drying is 5.3 tons.

Using the same approach as before, let's denote the mass of the dried pears as D.

According to the given information, the initial mass before drying is 5.3 tons. This can be expressed as:

0.15M = D

Substituting the value of M from the previous calculation (M = 24 tons), we have:

0.15 * 24 tons = D

Calculating this, we find:

D = 3.6 tons

Therefore, the mass of the dried pears is 3.6 tons when the initial mass before drying is 5.3 tons.

In summary: - The initial mass of the pears before drying was 24 tons. - The mass of the dried pears is 3.6 tons when the initial mass before drying is 5.3 tons.
