Decimal numbers are based on powers of ten. Each digit after the decimal point represents a fractional value, such as tenths, hundredths, thousandths, and so on. For example, in the number 8.455:

• The 4 is in the tenths place, so its value is 4 × 0.1 = 0.4
• The 5 is in the hundredths place, so its value is 5 × 0.01 = 0.05
• The 5 is in the thousandths place, so its value is 5 × 0.001 = 0.005

Understanding the place value of each digit helps with rounding, comparing numbers, and performing arithmetic with decimals. It's especially important in fields like science, finance, and engineering.
