Questions & Step-by-Step Solutions
A pie chart shows the percentage of time spent on various activities by a student. If 'Study' takes up 40% of the time and the total time is 50 hours, how many hours are spent studying?
Step 1: Understand that the total time is 50 hours.
Step 2: Know that 'Study' takes up 40% of the total time.
Step 3: Convert the percentage (40%) into a decimal by dividing by 100. So, 40% becomes 0.40.
Step 4: Multiply the total time (50 hours) by the decimal (0.40) to find the hours spent studying. So, 50 hours * 0.40 = 20 hours.
Step 5: Conclude that the student spends 20 hours studying.
