- 4 is in the tenths place and 5 is in the hundredths place
- Since the digit in the hundredths place (5) is greater than or equal to 5, add 1 to the digit in the tenths place (4)
- 1 + 4 = 5, so the digit in the tenths place becomes 5
- The digits to the right of the tenths place are dropped
- 0.4545 rounded to the nearest tenth (one decimal place) = 0.5
