Q: In a pie chart showing the distribution of time spent on different subjects, if Mathematics takes up 35% of the time and the total study time is 40 hours, how many hours are spent on Mathematics?
Solution: 35% of 40 hours = 0.35 * 40 = 14 hours.
Steps: 4
Step 1: Understand that 35% means 35 out of every 100 parts.
Step 2: Convert 35% into a decimal by dividing 35 by 100, which gives you 0.35.
Step 3: Multiply the total study time (40 hours) by the decimal (0.35) to find the hours spent on Mathematics.
Step 4: Calculate 0.35 * 40, which equals 14 hours.
