Question

In a local​ town, 4/5 of the​ voting-age population is registered to vote. If 7/8 of the registered voters voted in the election for​ mayor, what fraction of the​ voting-age population​ voted?

Answer 1

`(7)/(10)` of voting age population voted

Explanation:

In order to find out that fraction we just have to mulitply the fraction of the people that were registered by the fractions of the people that were registered and voted. And so we get...

`((4)/(5))((7)/(8)) = ((4)(7))/((5)(8)) = (28)/(40) = (7)/(10)`
