it is a 52%

138 questions right and 12 questions wrong
To calculate your grade, you divide the number you got correct (9) by the total number of questions (12), which would give you 75%.
toget 80% you need .8 x 15 = 12 questions right. That means you can 15-12 = 3 questions wrong

70% were correctly answered.
40 minus 28 = 12 were wrong
138 questions right and 12 questions wrong
Assuming that each question carries the same one mark: 88% right = 100% - 88 % wrong = 12 % wrong → 12 % of 44 = 12/100 × 44 = 5.28 wrong Assuming that your percentage right was truncated (and not rounded to 89% to the nearest whole number), you got 5 wrong.
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.
that has happened to me in the forth grade. i wrote 7+4=11 and she said no its 12, you got that one wrong!
Ans: 30%. Working: 40-28=12 12/40 x100%=30%
