Question

При обработке детали из оливки массой 40 кг в отходы ушло 3,2 кг.Какой процент составляет масса детали от массы отливки?

Answer 1

1) 40-3.2=36.8(кг)-масса детали

2) (36,8/40)*100=92%

  Ответ:92%

Answer 2

Calculating the Percentage of the Detail's Mass from the Casting's Mass

To calculate the percentage of the detail's mass from the casting's mass, we can use the following formula:

Percentage = (Mass of Detail / Mass of Casting) * 100

Given: - Mass of the casting = 40 kg - Mass of the waste = 3.2 kg

We can calculate the mass of the detail using the formula: Mass of Detail = Mass of Casting - Mass of Waste

Mass of Detail = 40 kg - 3.2 kg = 36.8 kg

Now, we can calculate the percentage: Percentage = (36.8 kg / 40 kg) * 100

Calculation

Percentage = (36.8 / 40) * 100 = 92%

Therefore, the mass of the detail is 92% of the mass of the casting.
