You have to divide the top and the bottom numbers in the fraction ( numerator, denominator ), and you will always get a mixed number, or a mixed number in lowest terms.

16 2/3 is a reduced mixed number as a decimal it is 16.666666666666666666 (This is approx. since the 6's after the decimal are infinite. The most acturate way to write this number is as 16 2/3.

2.54, which is in decimal form, can be rewritten, in fractional form, as 254/100 or as a mixed number as 2 54/100 which can then be reduced to 2 27/50 which can no longer be reduced without getting a decimal. Your final answer should be 2 27/50.

0 is the whole number part of the mixed number and 7011/10000 is the fractional part. (Because 7011 and 10000 are relatively prime, it cannot be reduced further.)
