15 / 31 * 100% = 48.39%
Usually you need to obtain 50% or over to pass an exam or test.
If you missed 12, then you got 31 correct [43-12=31]. If all questions are weighted equally, then 31/43 = 0.721 or 72.1 %, so your grade is 72.
31/40 = 77.5%.
84.5% B
87% or B+
Out of 100? (31/45 * 100) = 68.9 (rounded to 3 significant figures).The letter grade depends on your teacher's marking system.

100 - 69 = 31, and it's percent, so it's .31 .31*30 = 9.3, but you must round down or up (down to get more than 69%), so you can miss 9 questions and still fail.
31
70% of 31 questions is 31*70/100 = 21.7 questions. However, since you cannot have 0.7 questions, the answer is one of: 21 questions = 68% or 22 questions = 71%
16 31-15=16 15-31=-16
