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 3.9192:

• The 9 is in the tenths place, so its value is 9 × 0.1 = 0.9
• The 1 is in the hundredths place, so its value is 1 × 0.01 = 0.01
• The 9 is in the thousandths place, so its value is 9 × 0.001 = 0.009
• The 2 is in the ten thousandths place, so its value is 2 × 0.0001 = 0.0002

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.
