If you got a zero on a test and the test counts for 30% of your grade and you have an 81 in the class how much would your grade go down?

    (0.7 * 81% = 0.3 * 0%) = 56.7%

    There is a basic problem with the 100 point scale, where an F covers 60 points, usually, and all the other grades cover much fewer points. A 0 averaged with a 100 is a 50-- a failing grade. How did you manage to get a 0 on a test? Did you just not take it? Seriously, I teach teachers, and I've had an awful time convincing them that a 0 is not the same as an F. If you average a C and an F, you get a D. If you average an 81 and a 0, you get a 40.5. 

    70 times 81 equals 5670.  Then 30 times zero equals 0. Divide that by 100, and you get 56.70- a failing grade in most school systems. Depending on why you got the zero, you might need your parents to contact the teacher and the principal about why the mathematics on this are all wrong, and you shouldn't fail the class.

    If this test is the only assignment in this 30% category, then your grade would go down by 30%.
