If there are 50 questions on a test and 19 are missed, what would be the grade?

How would I solve this? Thanks

31/50 = ?

Change the decimal answer to a percent.

62% ... thanks!

First of all you would need to know the value of one question = one point, two points, etc.

If each question were worth 1 point, on a base of 100, double the 50 = 100, either double 19 = 38 to subtract from 100 = 62 which is like a D- on most grading scales. At any rate you would have 62%.

also, you can subtract 19 from 50, giving you 31 and if you divide 31 by 50 you end up also with .62 or 62%.

In a grade book it would look like 62/100 or 31/50.

Hi I took a final exam today for my math class. There were 50 questions worth 2 points each can you tell me how man I would have needed to get right to pass the exam? Thanks

To determine the grade on the test, you need to know the total number of questions and the number of questions missed. In this case, there are 50 questions on the test and 19 questions were missed.

To calculate the grade, follow these steps:
1. Subtract the number of missed questions (19) from the total number of questions (50): 50 - 19 = 31.
2. Divide the result from step 1 by the total number of questions (50): 31 ÷ 50 = 0.62.
3. Multiply the result from step 2 by 100 to get the percentage: 0.62 × 100 = 62.

The grade would be 62%.
