Best Answer

38 = 2 x 19 (notice that 19 has no smaller factors)

63 = 3 x 3 x 7

Since the two numbers (38 and 63) don't contain any of the same numbers there is no number that goes into both of them.

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?
