A quality control process finds 77.6 defects for every 9,700 units of production. What percent of the production is defective?
KonstantinChe [14]

The 0.8% of the production is defective if a quality control process finds 77.6 defects for every 9,700 units of production.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A quality control process finds 77.6 defects for every 9,700 units of production.

The percent of the production is defective:

\rm = \dfrac{77.6}{9700}\times 100

= 0.8 %

Thus, the 0.8% of the production is defective if a quality control process finds 77.6 defects for every 9,700 units of production.
