Write \( \frac{5}{18} \) as a decimal. If necessary, use a bar to indicate which digit or group of digits repeats.

To convert 5/18 to a decimal, divide 5 by 18: • 18 goes into 5 zero times, so write down 0. • Put a decimal point and bring down a 0 (making it 50). • 18 goes into 50 two times (2 × 18 = 36) with a remainder of 50 − 36 = 14. • Bring down another 0 (making it 140). 18 goes into 140 seven times (7 × 18 = 126) with a remainder of 140 − 126 = 14. • Since the remainder 14 is repeating, the digit 7 will repeat indefinitely. Thus, the decimal representation of 5/18 is 0.2̅7, where the bar indicates that the digit 7 repeats.
