You do the cross multiplication. For example, if you got 32 points on a 47 point exam, then you multiply 32 by 100, then divide the answer by 47. This makes that you got aprox. 68% in your exam.
Visual:
32 ?
--- = ---
47 100
1) 32 x 100 = 3200
2) 3200 / 47 = 68.051...
So..
32 68
--- = ---
47 100
Hence, 68%
-- Your score is 57 percent.-- Your grade depends on whatever the teacher decides is the grade for 57 percent.-- Personally, I can't imagine a teacher awarding a passing grade for a score of 57 percent.
Since that is approx one third of 1 percent, the grade would be a spectacular fail.
It's an A- That is pretty good for math!
any number divided by hundred for ex: 5/100
