Question

Describe how to round 3.987 to the nearest tenth

Answer 1

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! (:

Answer 2

so u basically round 8 which is 10 and then add the 1 from 10 to 9 which is 10 and add the 1 to 3 which is 4
