To find the grade percentage for 8 wrong out of 30, first calculate the number of correct answers, which is 30 - 8 = 22. Then, divide the number of correct answers by the total number of questions: 22/30 = 0.7333. To convert this to a percentage, multiply by 100, resulting in approximately 73.33%. Therefore, the grade is about 73%.
