Round off the decimal given to the nearest hundredths 5.099?

Well, isn't that a happy little decimal we have there? To round 5.099 to the nearest hundredths, we look at the digit in the thousandths place, which is 9. Since 9 is greater than or equal to 5, we round up the hundredths place to get 5.10. And just like that, we've created a lovely rounded decimal to work with.
