What grade would you get if there were 57 questions and you got 38 right?
You got 38 out of 57. "Out of" translates mathematically into "divided by" 38 divided by 57 = 38/57 You could use a calculator for these "big numbers" ...or notice that 38 = 19x2 and 57 = 19x3 So 38/57 = 2/3 = two thirds = 0.667 (actually 0.666666666...) = 66.7% = 67% (rounded off) What grade is this? Who knows -- that's up to the teacher!
