Multiple Choice

In a survey, 70% support a policy. If 500 people are surveyed, how many support it?

Convert the percentage to a decimal and multiply by the total surveyed. 70% becomes 0.70, so 0.70 × 500 = 350. Another way is seven-tenths of five hundred: 500 ÷ 10 = 50, times 7 equals 350. So 350 people support the policy. The other numbers correspond to different percentages (for example, 450 would be 90% of 500, and 200 would be 40%), which aren’t the 70% stated.
