if you are looking for a grade that is out of 100, take the amount of points you got and divide by 20. then multiply by 100 for example if you got 17 out of 20 points 17/20=.85 multiply by 100 the grade is an 85% now on a 100 point scale
67% or D+
14 points.
As a percentage 18 out of 20 is 90%
60 D
every question is 2 points
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.
you minus the two sets of # first then find out what "a" is always the # after the = minus the # before "a" 30 + a = 50 a = 50 - 30 a = 20 30-30=50-30 (50-30=20) 0+a=20 a=20 if a = 20 30+a=50 30+20=50 50=50 therefore a=20
The lack of 20 points will put you in a C+ to C grade. Miss another one and you will be in the D range. Get to work.
