Question

The possibility of building a new city park, 12 out of 15 people thought that building the park was a good idea. There were 600 people surveyed. What percent do not think the park is a good idea?

Answer 1

If 12 of 15 thought it was a good idea then (15-12)=3, 3 out of 15 thought is was not a good idea...

Percent means per one hundred

p/100=3/15

p=3(100)/15=20%

So 20%, or 120 people of the 600, thought the park was not a good idea.

Answer 2

To find the answer, you have to cross multiply 3 by 100 to get 300

Next, you divide 300 by 15 to get 20

Your answer is that 20% of people do not think the park is a good idea
