- 1 is in the tenths place and 6 is in the hundredths place
- Since the digit in the hundredths place (6) is greater than or equal to 5, add 1 to the digit in the tenths place (1)
- 1 + 1 = 2, so the digit in the tenths place becomes 2
- The digits to the right of the tenths place are dropped
- 4.1666 rounded to the nearest tenth (one decimal place) = 4.2
