You multiply 61.5 by 100 (to find a percent). Then divide that number by 80.
That would be about a 77%. That is considered a D (where I'm from).
64%= 32/50 * 100%= 0.64 * 100%= 64%If the acorrect answer has the same bearing as the wrong answer then the grade percentage is 64%
c
A+
The answer depends on the grade boundaries.
Generally 90-100 % will give you letter grade A
D
Not sure if your 64 is a paper or test grade. We also don't know the number of points possible. If you got a 64 out of 70 possible that would be an A , but if you got 64 out of a 100 that would be a low C nearly a D.
A?
letter grade=C your dumb
Grade scale 100-90=A 89-80=B 79-70=C 69-60=D 59-0=F So a 64 is a D
32% is a F
83% or B
