I think I must be asking my question wrong, but what is my number grade if I missed 36 out of 85 questions. For example if I missed 1 out of 10 I know my grade would be a 90.

If you're looking for a percentage --

85 - 36 = 49

49 / 85 = 0.576 = 58%

If there is 19 questions on a math test and you missed 7 what would your grade be

To determine your number grade, you need to calculate the ratio of the number of questions you answered correctly to the total number of questions, and then convert that ratio into a percentage. Here's how you can do it:

Step 1: Subtract the number of questions you missed from the total number of questions to find the number of questions you answered correctly.
Correctly answered questions = Total questions - Missed questions
Correctly answered questions = 85 - 36
Correctly answered questions = 49

Step 2: Calculate the ratio of correctly answered questions to the total number of questions, and multiply it by 100 to get a percentage.
Grade percentage = (Correctly answered questions / Total questions) * 100
Grade percentage = (49 / 85) * 100
Grade percentage ≈ 57.65%

Therefore, if you missed 36 out of 85 questions, your grade would be approximately 57.65%.
