Answer:
10
Explanation:
Round to the nearest whole number. Note the number in the tenth's place value (directly right of the decimal point). It is a 5. By rule of rounding, if the number is 5 and greater, round up, if 4 and less, round down. In this case, it is a 5, so round up:
9.511 => 9 + 1 = 10
10 is your answer.
