Step-by-step explanation:
If you are referring to the attached picture, then the answers would be the answers above. The first two fractions are not exact because they are repeating decimals (they go on endlessly).
For example, if you divide 1 by 9, you will end up with 0.11111 because each time you subtract 9 from 10, you will get 1 and when you drop a zero, you'll end up with 10 again.
Decimals that are the exact decimal equivalent of a fraction would be one that is non-repeating, like the last one.
