128% as a decimal

Professor Greenline Explaining Math Concepts

This is a simple question on converting percentages to decimals. Firstly, we need to understand percentages and decimals. A percentage represents a part of a hundred. The symbol % stands for percent, which means per hundred. A decimal is a way to represent numbers that are not whole, using a period (.) 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.
