What is a situation in which you would use fractions to express a number less than one What is a situation in which decimals seem to work better?
The fraction 1/3=0.3333333... In this case it is better to use fractions just like in all cases. There will be no case when decimals will work better than fractions however, if a test says to use decimals; USE THEM!

When you are dividing two repeating decimals is it easier to add them as they are or to change them to fractions first?
It is not clear why you would wish to add them! Changing them to fractions is generally the better option because it averts rounding errors.
