If you get 8 out of 20 questions wrong, you have answered 12 questions correctly. To find your score as a percentage, you can divide the number of correct answers (12) by the total number of questions (20) and then multiply by 100, resulting in a score of 60%.
60% right, 40% wrong.
48 less than 12:= 12 - 8= 4
This is wrong. It should be 16 should be replaced by 10 2+2=4, 4x2=8, 8+2=10, 10x2=20, 20+2=22, 22x2=44, 44+2=46
8/20 is 40 %
X=16 (i failed Algebra so it's probably wrong :D )
20
60% right, 40% wrong.
percentage of correct answers = 60%(20 - 8)/20 * 100% = 12/20 * 100% = 60% In most school systems that translates to F - for FAIL
48 less than 12:= 12 - 8= 4
If there are 20 questions then each question is worth 5 points because 100 total points divided by 20 equals 5.If you missed 8 questions then 8 times 5 points equals 40 points wrong, so you have to subtract that from 100 to get a grade of 60. Study harder next time.
20 + 8 = 28 20 - 8 = 12 20 x 8 = 160 20/8 = 2.5
This is wrong. It should be 16 should be replaced by 10 2+2=4, 4x2=8, 8+2=10, 10x2=20, 20+2=22, 22x2=44, 44+2=46
8
8/20 is 40 %

If you get 20 wrong out of 50 questions what is your grade?
20 wrong.
