How to Calculate Percentage of a Number?
Calculating percentages is an essential life skill, especially for percentage worksheets grade 6 and beyond. The easiest method to calculate a percentage of a number is to convert the percentage into a decimal first.
For example, "percent" literally means "per 100." So, $20\%$ is the same as $20 \div 100$, or $0.20$.
To solve What is 20% of 150?:
1. Convert 20% to decimal: $0.20$
2. Multiply by the number: $0.20 \times 150 = 30$
Our calculating percentages math drills help you practice this "decimal multiplication" method until it becomes second nature.
