Roman missed 7 out of 90 problems on a math test. What percent of the questions did he answer correctly? Round to the nearest tenth of a percent.

Answer:92.22 percent

Step-by-step explanation:the no of correct answers = number of total questions - missed or failed answers

90 - 7 = 83

The ratio of the correct answers to the total questions = 83/90 = 0.922

Convert ratio to percent

0.9222 * 100 = 92.22percent
