how do you use fractions, decimals, and percentages in marinebiology and archeology ????? i need help!!!!!!

I'd say you use them the same way as in any other fields of endeavor. Any time you have something besides just whole numbers, you have fractions and decimals.
Just think of any project where you have to measure of evaluate something, and you are likely to encounter fractions and decimals.
Now, if you don't know how to use them at all, you have some serious studying to do long before entering any field of realworld work.
