Statistics show that the sales force of a certain company successfully closed 990 sales out of 1,100 sales calls. What was their percent success rate?

To find a success rate we can take the amount of times the trial was successful (in this case a sale was made) and divide it by the total number of trials (in this case, the total number of calls made).

If we take that idea and apply it to this problem, we would have:

990/1100 = 0.9

To convert a decimal to a percent, you multiply by one hundred, which gives you 90%.

**This company had a 90% success rate.
