121% as a decimal

Professor Greenline Explaining Math Concepts

Converting percentages to decimals is a fundamental concept in mathematics. A percentage represents a part out of 100. To convert a percentage to a decimal, we need to understand both percentages and decimals. A decimal uses a 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.
