260/500 = 130/250 = 26/50 = 13/25
you put the amount flown over the total amount and then factor from there! i first divided the 260 and 500 by 2 (since both of the numbers are divisible by 2), which gave me 130/250. then divided by 5, and lastly by 2. final answer, reduced completely, is 13/25. hope this helps!
