1 1 1
Number 9 . 9 9
Rounded Number 1 0 . 0
  • 9 is in the tenths place and 9 is in the hundredths place
  • Since the digit in the hundredths place (9) is greater than or equal to 5, add 1 to the digit in the tenths place (9)
  • 1 + 9 = 10, so the digit in the tenths place becomes 0, and 1 is added to the digit in the ones place (9)
  • 1 + 9 = 10, so the digit in the ones place becomes 0, and 1 is added to the digit in the tens place (0)
  • 1 + 0 = 1, so the digit in the tens place becomes 1
  • The digit in the hundredths place is dropped
  • 9.99 rounded to the nearest tenth (one decimal place) = 10.0
