What is Rounding to the Nearest Tenth?

Rounding to the nearest tenth means rounding a number to 1 decimal place. The tenth place is the first digit after the decimal point, representing tenths (0.1, 0.2, 0.3, etc.).

Understanding Place Values

Example: 12.456

  • • 1 = Tens place
  • • 2 = Ones place
  • • 4 = Tenths place ← We round to this!
  • • 5 = Hundredths place ← Look at this to decide
  • • 6 = Thousandths place

Step-by-Step Rounding Process

  1. Identify the tenths place - The first digit after the decimal
  2. Look at the hundredths place - The second digit after the decimal
  3. Apply the rounding rule:
    • If hundredths digit is 5 or greater → Round UP
    • If hundredths digit is less than 5 → Round DOWN (keep tenths digit same)
