Question

Абрикосы при сушке теряют 4/7 своей массы.Сколько сушеных абрикосов получится из 140 кг свежих?

Answer 1

1)140:7=70(кг) 2)70*4=280(аб)

Answer 2

4/7 * 140 = 80 (кг) теряют абрикосы
140 - 80 = 60 (кг) получится

Answer 3

Calculating the Quantity of Dried Apricots

To calculate the quantity of dried apricots obtained from 140 kg of fresh apricots, we can use the fact that apricots lose 4/7 of their mass when dried.

Step 1: Calculate the mass of the apricots after drying. The mass of the dried apricots can be calculated using the formula: \[ \text{Mass of dried apricots} = \text{Mass of fresh apricots} - \left( \frac{4}{7} \times \text{Mass of fresh apricots} \right) \]

Step 2: Calculate the quantity of dried apricots. The quantity of dried apricots can be calculated by dividing the mass of dried apricots by the average mass of a single dried apricot.

Calculation

\[ \text{Mass of dried apricots} = 140 - \left( \frac{4}{7} \times 140 \right) \] \[ \text{Mass of dried apricots} = 140 - \left( \frac{4}{7} \times 140 \right) = 140 - 80 = 60 \text{ kg} \]

Assuming the average mass of a single dried apricot is 0.02 kg, the quantity of dried apricots can be calculated as: \[ \text{Quantity of dried apricots} = \frac{\text{Mass of dried apricots}}{\text{Average mass of a single dried apricot}} = \frac{60}{0.02} = 3000 \]

Answer: Therefore, from 140 kg of fresh apricots, you would obtain 3000 kg of dried apricots.
