Question

A city data report shows that 13
of the parks in that area have a flagpole. If the city decides to install more flagpoles in another 13
of the parks, what is the total fractional portion of parks that have flagpoles?

Answer 1

Assuming the city adds flagpoles to a different additional 1/3 of the parks, the total is
1/3 + 1/3 = 2/3.

(If instead they meant 1/3 of the remaining parks, the total would be 1/3 + (2/3)(1/3) = 5/9.)
