100% as a decimal

Professor Greenline Explaining Math Concepts

Understanding percentage to decimal conversion is straightforward. A percentage is a fraction out of 100. The symbol "%" means per hundred. Converting a percentage to a decimal involves dividing by 100. Decimals use a point (.) to separate the whole number from the fractional part. To the left of the decimal point are whole numbers, and to the right are fractional values.
