How to Round to the Nearest Cent: A Step-by-Step Guide

Rounding to the nearest cent is straightforward when you follow these steps. The standard method relies on examining the digit in the thousandths place:

1. Identify the Cents Place: Look at the digit in the hundredths place (the second digit after the decimal point). This is the cent we want to round to.
2. Check the Thousandths Place: Examine the digit immediately to the right of the cents place (the thousandths place).
3. Apply the Rounding Rule:
   • If the digit in the thousandths place is 5 or greater, round up the cents place by one.
   • If the digit in the thousandths place is 4 or less, leave the cents place as it is.
4. Drop Remaining Digits: Remove all digits to the right of the cents place.

Examples:

• Example 1: Round $3.456 to the nearest cent.
  • The cents place is 5.
  • The thousandths place is 6 (which is 5 or greater).
  • Round up: $3.45 becomes $3.46.
• Example 2: Round $12.723 to the nearest cent.
  • The cents place is 2.
  • The thousandths place is 3 (which is 4 or less).
  • Round down: $12.723 becomes $12.72.
• Example 3: Round $99.995 to the nearest cent.
  • The cents place is 9.
  • The thousandths place is 5 (which is 5 or greater).
  • Round up: $99.99 becomes $100.00.
