Questions & Step-by-Step Solutions

In a survey, 70% of people like chocolate. If 200 people are surveyed, how many like chocolate?
  • Step 1: Understand that 70% means 70 out of every 100 people.
  • Step 2: We need to find out how many people like chocolate out of 200 surveyed.
  • Step 3: Convert 70% to a decimal. 70% as a decimal is 0.7.
  • Step 4: Multiply the total number of people surveyed (200) by the decimal (0.7).
  • Step 5: Calculate 0.7 * 200, which equals 140.
