Questions & Step-by-Step Solutions
A pie chart illustrates the percentage of time spent on various activities in a day. If 30% of the time is spent sleeping, how many hours are spent sleeping in a 24-hour day?
Step 1: Understand that a day has 24 hours.
Step 2: Identify that 30% of the day is spent sleeping.
Step 3: Convert the percentage to a decimal by dividing 30 by 100, which gives you 0.30.
Step 4: Multiply the total hours in a day (24) by the decimal (0.30) to find the hours spent sleeping: 0.30 * 24.
Step 5: Calculate the result of the multiplication: 0.30 * 24 = 7.2 hours.
Step 6: Round 7.2 hours to the nearest whole number, which is 8 hours.
