Question

On a cutting operation 2 sq ft of sheet steel is wasted for every 32 sq ft used. What is the percent waste?

(Type a whole number or an exact decimal. If the decimal does not terminate. Round to the one decimal place)

Answer 1

Explanation:

Here are the steps to calculate the percent waste of sheet steel:

Determine the amount of steel wasted per unit of steel used. The problem tells us that 2 sq ft of steel is wasted for every 32 sq ft used. Therefore, the waste-to-use ratio is 2/32.

Simplify the waste-to-use ratio, if necessary. In this case, the ratio can be simplified by dividing both the numerator and denominator by 2:

2/32 = 1/16

Convert the waste-to-use ratio to a percentage. To do this, we multiply the simplified ratio by 100:

1/16 * 100 = 6.25

Round the result, if necessary. The problem asks for a whole number or an exact decimal, so we round the result to one decimal place:

6.25 rounded to one decimal place is 6.3.

Therefore, the percent waste of sheet steel is 6.3%.

Answer 2

Answer: To find the percent of waste, we need to first determine the fraction of waste.

For every 32 square feet used, 2 square feet are wasted. This can be expressed as:

2/32 = 1/16

So, the fraction of waste is 1/16.

To find the percentage, we need to multiply this fraction by 100:

1/16 * 100 = 6.25

Therefore, the percent of waste is 6.25%.
