The easiest way to find out is to divide the amount of points you got divided by the total number of points. 103 divided by 200 is 0.515. Turn that number into a percent by changing the decimal place two places to the right. You got 51.5% right, or a 51.5 (ouch).
As a percentage 125 out of 200 points = 62.5%
171.5 points out of 200 points is equivalent to 85.75%. In a standard grading system, this would typically fall within the range of a high B grade.
You would get 97.5% or an A ;)
49% F
71.5% C
if you get a 150 out of 200 then you will a 75% which is a C average
103 over 200 already is in simplest form
103 / 200 is already in lowest terms as a fraction. The decimal form is 0.515
80%, so probably a C+, or perhaps a B-.
little over 60 percent
