Question

During one election, Springtown 7 of every 9 people who voted favored remodeling the city swimming pool. Springtown has 36,000 eligible voters. In this election 5 of every 8 eligible voters actually voted. How many people voted for remodeling the city swimming pool?

Answer 1

First we have to figure out how many people actually voted.

 

Population is 36,000 eligible voters

5 out of every 8 voted. 5/8 of these voted. That is 0.625(5 divided by 8)...

multiple 36,000*0.625=22,500 people actually voted.

 

Out of the 22,500 who voted, 7 out of every 9 people voted yes to remodel city swimming pool.

 

7/9=0.777777778

so multiple 0.7777777778 by 22,5000=17,500

 

17,500 voted yes to remodeling the city swimming pool
