Understanding Percentages: A percentage is a fraction or ratio expressed as a number out of 100. For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2. Calculating percentages involves understanding the relationship between a part and a whole.

Calculating "What Percent of 25 is 20?"
