Question

what is the percent of decrease from 9 to 6? round your answer to the nearest tenth of a percent and include a percent sign (%).

Explanation:

Step1: Calculate the amount of decrease

The original value is 9 and the new value is 6. The amount of decrease is $9 - 6=3$.

Step2: Use the percent - decrease formula

The percent - decrease formula is $\text{Percent Decrease}=\frac{\text{Amount of Decrease}}{\text{Original Amount}}\times100\%$. Substitute the values: $\frac{3}{9}\times100\%=\frac{1}{3}\times100\%\approx 33.3\%$.

Answer:

33.3%
