Q
Q: In a survey, 70% of respondents said they exercise regularly. If 350 people responded, how many do not exercise regularly? (2023)
Solution: People who exercise = 70% of 350 = 245; People who do not exercise = 350 - 245 = 105.
Steps: 5
Step 1: Find out how many people responded to the survey. The total number of respondents is 350.
Step 2: Calculate how many people exercise regularly. Since 70% of the respondents exercise, we need to find 70% of 350.
Step 3: To find 70% of 350, multiply 350 by 0.70 (which is the decimal form of 70%). So, 350 * 0.70 = 245.
Step 4: Now, to find out how many people do not exercise regularly, subtract the number of people who exercise from the total number of respondents. So, 350 - 245 = 105.
Step 5: The final answer is that 105 people do not exercise regularly.
