31.75 rounded to the nearest tenths

1 answer:

3 0

The answer is 31.8 because when you round something if the last number is 5 or above then you round the next number in front of it up by 1. And if the number is below 5 then you don't do anything to the number. The tenths decimal place is the first number after the decimal point and the second number after the decimal point is the hundredths decimal place.
