You look at 3.1 and you say to yourself . . .
"Self ! Look at that number. The next bigger whole number is 4, and the next smaller whole number is 3. Which one is nearer to 3.1 ? Did you say 3 is ? I'm so proud of you !"

To round 3.1 to the nearest whole number, look at the digit after the decimal, which is 1. Since 1 is less than 5, you round down, so the result is 3.
