Final answer:
To find the percentage of questions that Mario answered correctly, divide the number of questions answered correctly by the total number of questions and multiply by 100%.
Step-by-step explanation:
To find the percentage of questions that Mario answered correctly, we can use the formula:
Percent correct = (Number of questions answered correctly / Total number of questions) x 100%
In this case, Mario answered 5 out of 8 questions correctly. Plugging these values into the formula, we get:
Percent correct = (5 / 8) x 100% = 62.5%
Therefore, Mario answered approximately 62.5% of the questions correctly.
