81% as a decimal
This is a simple question on decimal conversion. To begin, we need to understand percentages and decimals. A percentage represents a part of 100. It is a way to express a number as a fraction of 100. A decimal is a way to represent the number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
