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

Step-by-step 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 $9x=9\times 61=549$
