Set up the proportion
346/846 = x/100
Then solve for x.
To solve for x do 346×100/846
346×100=34600
34600/856=40.89
Since it isn't specified what to round to, I'm going to round to the nearest whole number. So 40.89 becomes 41
It then asks what percent did not vote, 41% is the amount that did vote, so we can find the percent that did not vote be subtracting 41% from 100%
100%-41%= 59%
59% of the neighborhood did not vote
