Numbers, decimals, and percentages play crucial roles in mathematics.
Numbers are composed of digits from 0 to 9, including a decimal point. Place value determines the value of each digit based on its position relative to the decimal point.
Decimals represent numbers between whole numbers and can be converted to fractions. They are essential for expressing quantities precisely.
Percentages show values out of 100 and are identified by the % symbol. Converting percentages to decimals involves dividing by 100 and moving the decimal point two places to the left.
