    If all the questions were worth 1 point, then 69% yes...but in math that's usually not the case since there's a lot of steps in math.

    If all of the questions are worth the same amount of points, this is how you calculate your grade. Divide the number of problems you got right by the total number of problems on the test. If you have 42 problems total and you have 29 (42 minus 13)problems right then, that's 29 /42 = 69% ( a D)

    13 in 42 = x in 100. x= (100x13)/42 = aprox. 31.

    100-31 = 69.

    Your grade would be 69%

    It's 69%. I'd say that's probably a failing grade.

    42-19=29

    29/42= 0.69047619

    number of correct answers, divided by total possible correct.

    Around a 69 or 70.

    divide 29 by 42 and move the decimal over two places and thats your grade

    It depends on how many points each question was worth. If each question was worth the same amount of points, your percentage would be about 69%, which I believe is a D+ or C-.
