Topic: Rounding Numbers

ClassBrain Visitor:

i don't know how to round very well. please help me.

ClassBrain Response:

When learning how to round numbers, it’s important to look at the very last number.

For example, let’s start with the number 502.

What’s the very last number?

It’s 2 right?

And what’s the very last number of 507?

It’s 7 right?

This is the most important part of rounding. Once you have decided what the last number is, the next question is do you round up or down?

The rule is this, if the last number is 1,2,3, or 4, then you round down.

If the last number is 5,6,7,8, or 9, then you round up.

So, if we were rounding 502, then we already know that the last number is 2. This means we round down. The number 502 rounded to the nearest tenth would be 500.

If we were rounding the number 507 we already know that the last number is 7. This means we round up. The number 507 rounded to the nearest tenth would be 510.

If you have any more questions, don’t be afraid to ask your teacher for extra help. That’s what they are there for and trust me, they won’t mind! :-)
