If i get 3 problems wrong on a 12 question math paper, what grade would i get?

If you got 3 questions wrong on a 12 problem math paper, to figure out how many you got right you must subtract the number you got incorrect (3) from the total number (12).

12-3=9

To figure out your grade, you have to divide how many you got correct (9-see above) by the total number of questions (12).

9/12 = 0.75

If you multiply this decimal by 100, you get the equivalent percentage of 75%.

Therefore, you would have gotten a 75% on the paper.

Hope this helps!
