Question

During an local election the ratio of teens to adults who voted was 9.3. If 732 people voted how many were teens

Answer 1

Answer: 549

Explanation:

Given

The ratio of teens to adults is 9:3

The total number of people who voted is 732

let 9x be the no of teens and 3x be the no of adults such that their ratio is 9:3

So, we can write

`\Rightarrow 9x+3x=732\\\Rightarrow 12x=732\\\Rightarrow x=61`

No of the teens were
`9x=9* 61=549`
