Question

из 800г свежей черники получили 320 г сушеной.На сколько процентов уменьшилась масса черники при сушке?

Answer 1

Calculation of Percentage Decrease in Weight of Blueberries

To calculate the percentage decrease in weight of blueberries during the drying process, we need to compare the initial weight of fresh blueberries with the final weight of dried blueberries.

Given: - Initial weight of fresh blueberries = 800 g - Final weight of dried blueberries = 320 g

To find the percentage decrease, we can use the following formula:

Percentage Decrease = ((Initial Weight - Final Weight) / Initial Weight) * 100

Substituting the given values into the formula:

Percentage Decrease = ((800 g - 320 g) / 800 g) * 100

Simplifying the equation:

Percentage Decrease = (480 g / 800 g) * 100

Calculating the percentage decrease:

Percentage Decrease = 0.6 * 100 = 60%

Therefore, the weight of the blueberries decreased by 60% during the drying process.
