The tenth digit is the second to the right, after the decimal, so 8. If you look at the hundredths digit, you see it is a 7. Is 7 closer to 1 or 10? 10, so you would round the 8 up to 9, instead of leave it at 8. If the hundredths digit was closer to 1, you would leave it as a 8. Hope this helped! (:
