A pie chart shows the percentage of time spent on different activities in a day: sleeping 33%, working 25%, leisure 20%, and commuting 22%. What fraction of the day is spent on leisure and commuting?
Step 1: Identify the percentage of time spent on leisure, which is 20%.
Step 2: Identify the percentage of time spent on commuting, which is 22%.
Step 3: Add the percentages of leisure and commuting together: 20% + 22%.
Step 4: Calculate the total: 20% + 22% = 42%.
Step 5: Understand that 42% means 42 out of 100 parts of the day.
Step 6: Convert 42% to a fraction: 42% = 42/100.
Step 7: Simplify the fraction 42/100 by dividing both the numerator and denominator by 2: 42 ÷ 2 = 21 and 100 ÷ 2 = 50.
