How to Do Rounding With Whole Numbers

Hi, I'm Racquel Ward, learning specialist. Today, I'm going to show you how to round with whole numbers to the nearest tenths. If you have a number, like 649, and you wanna round it to the nearest tens, you wanna first notice the tens place. Then, you wanna notice the ones place. The ones place will tell you what you need to round to. If it's four or less, let it rest. If it's five or more, add one more. So, nine, goes with the five or more rule, so we're gonna round up to 50, giving us 650.
