Questions & Step-by-Step Solutions
A pie chart shows the percentage of time spent on different activities in a week. If 'Exercise' is represented by 15% of the chart, how many hours does this represent in a 168-hour week?
Step 1: Understand that a week has 168 hours.
Step 2: Know that 'Exercise' takes up 15% of the week.
Step 3: Convert the percentage to a decimal by dividing by 100. So, 15% becomes 0.15.
Step 4: Multiply the total hours in a week (168) by the decimal (0.15).
Step 5: Calculate 0.15 * 168 to find out how many hours are spent on exercise.
