Final answer:
Maria's test score is calculated by dividing the number of correct answers (22) by the total number of questions (25) and then multiplying by 100, resulting in a score of 88%.
Step-by-step explanation:
Maria took a history test with 25 questions and correctly answered 22 questions. To find her test score as a percent, you divide the number of correct answers by the total number of questions and then multiply the result by 100. So, Maria's score would be (22 correct answers / 25 total questions) × 100 = 88%.
This is how it calculates:
First, write the number of correct answers over the total number of questions as a fraction: 22/25.
Then, convert this fraction to a decimal by dividing 22 by 25, which equals 0.88.
Finally, multiply the decimal by 100 to get the percentage. So, 0.88 × 100 equals 88%.
Maria's test score expressed as a percent is 88%.
