Explanation:
Basically, percentages are how much a part is of a whole. We use the % symbol when describing percentages. As the word percentage has the term "per cent", this means per hundred, which is typically how percentages are based on.
For example, 45% means 45 out of 100. Think of how a dollar is worth 100 pennies, and 45 pennies make up 45% of those 100 pennies that contribute towards a dollar.
This is a simple explanation into getting started with percentages, but feel free to ask more questions if you have any!
