Question

A random survey showed that 35 out of 52 people plan to vote for Mr. Jones for Mayor. About how many people voted in the election, if 525 voted for Mr. Jones?

Answer 1

780 people

Explanation:

Basically, you have to find the scale by which the people who voted for Mr. Jones was, and then you have to multiply that scale by the number of people from the survey, which was 52. So here, 525 people voted for Mr. Jones, so we have to divide 525 by 35, which was the number of people that voted for Mr. Jones from the survey. You get 15 as the scale number, and multiply that by 52 to get 780, which is the total number of people that voted, assuming that these two are directly proportional.
