Complaints dropped from .7 to .07 per 1,000 people.

Is this equivalent to saying there was a 90 percent reduction in complaints?

You cut to 10% of original which is a 90% reduction.

Yes. A drop from 700 to 70 complaints is a 90 percent reduction.

Thank you both!

You're welcome.

To determine if a reduction from .7 to .07 complaints per 1,000 people is equivalent to a 90 percent reduction in complaints, we need to perform some calculations.

Step 1: Calculate the difference in complaints between the two values.
Difference = Initial Value - Final Value
Difference = .7 - .07
Difference = 0.63

Step 2: Calculate the percentage reduction.
Percentage Reduction = (Difference / Initial Value) * 100
Percentage Reduction = (0.63 / .7) * 100
Percentage Reduction ≈ 90%

Therefore, yes, a reduction from .7 to .07 complaints per 1,000 people is approximately equal to a 90 percent reduction in complaints.
