On a test, ellen answered 51 out of 64 questions correctly. what portion of her answers was correct? write your answer as a decimal rounded to the nearest thousandth.

Your problem does not indicate using the percent format, or at least that is not indicated here. But the wording "portion" seems like we should.

When a word problem is worded " out of " we express it like this:

51/64 - this indicates 51 divided by 64

Giving us 0.796875

Move the decimal two places to the right to change it to percent.

79.6875

Now round the 7 up to 8

79.688%

IF you do not feel this should be a percent answer - revert back to the original quotient - 0.796875 and round the 6 to a 7 giving you .797 - but that doesn't make much sense to say that you got .797.
