I have to teach someone how to round whole numbers. Can you describe the steps of how to round whole numbers?

Absolutely. Let’s take some example numbers:  
2.7 and 3.5.  We can say that: 2.7 rounded up is 3, and 3.5 rounded down is 3.  If you just want to know how to round up or down, you can do it with a bit of simple arithmetic.

The 3.5 example seems incorrect
