REM percentage of total sleep time is calculated as REM time divided by total sleep time. Given REM = 45 minutes and total sleep time = 275 minutes, what is the REM percentage?

Explanation:
REM percentage of total sleep time is the portion of sleep that occurs in REM, calculated by dividing REM time by total sleep time and multiplying by 100. With REM time of 45 minutes and total sleep time of 275 minutes: 45 ÷ 275 ≈ 0.1636. Multiply by 100 to convert to a percent: ≈ 16.36%. Rounded to the nearest whole percent, that’s 16%. So the REM percentage is about 16%.
