Percent defective is calculated as what expression?

Percent defective is the proportion of items that are defective in a batch. You determine it by dividing the number of defective units by the total number of units inspected, giving a fraction that represents the defect rate. To express it as a percent, multiply by 100%. So the expression is defective divided by total, with a multiplication by 100% to convert to a percentage. For example, 8 defective out of 320 gives 8/320 = 0.025, or 2.5% defective. The other forms don’t represent this rate: subtracting defective from total gives a difference, inverse ratios aren’t the defect rate, and multiplying defective by total isn’t a meaningful defect percentage.
