What is 85% as a decimal?

85% as a decimal is 0.85.

To convert a percentage to a decimal, you need to divide the percentage by 100. This is because "percent" means "per hundred," so 85% is the same as 85 per 100. When you divide 85 by 100, you get 0.85.

Another way to think about it is to move the decimal point two places to the left. For example, if you start with 85.0 (since 85% is the same as 85.0%), moving the decimal point two places to the left gives you 0.85.

Understanding how to convert percentages to decimals is useful in many areas of maths, including probability, statistics, and financial calculations. For instance, if you have a test score of 85%, you can express this as 0.85 when calculating your overall average. Similarly, if a bank offers an interest rate of 85%, you would use 0.85 in your calculations to determine how much interest you would earn.

Practising these conversions can help you become more comfortable with different forms of numbers and improve your overall mathematical skills.
