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 real-world work.

Fractions, decimals, and percentages are all mathematical concepts that can be applied to various fields, including marine biology and archaeology. Here's a breakdown of how they can be used:

1. Fractions:
- In marine biology, fractions can be used to represent ratios of different components within a sample, such as the proportion of plankton species in a water sample.
- In archaeology, fractions may be used to express the relative distribution of artifacts within a site. For example, a fraction could represent the percentage of pottery shards uncovered in a particular area.

2. Decimals:
- Decimals can be used in marine biology to express precise measurements, such as the length or weight of a marine organism.
- In archaeology, decimal notation might be used to quantify radiocarbon dating results or to represent the precise depth of stratigraphic layers during excavations.

3. Percentages:
- Marine biologists commonly use percentages to describe the composition or distribution of various elements in a sample, such as the percentage of pollution in a water body or the proportion of different coral types in a reef ecosystem.
- In archaeology, percentages can be used to describe the relative occurrence of different artifact types within a collection, the preservation status of archaeological materials, or the proportion of different cultural layers at a site.

To work with fractions, decimals, and percentages effectively, it's essential to first be comfortable with basic arithmetic operations like addition, subtraction, multiplication, and division. Additionally, using a calculator or spreadsheet software can simplify calculations and conversions. Practice problems and online resources are also available to strengthen your skills in these areas.
