In 1979 approximately 1/3 of the 37.3 million airline passengers traveling to or from the United States used Kennedy Airport. If the number of such passengers that used Miami Airport was 1/2 the number that used Kennedy Airport and 4 times the number that used Logan Airport, approximately how many millions of these passengers used Logan Airport that year?
(A) 18.6
(B) 9.3
(C) 6.2
(D) 3.1
(E) 1.6
D
divide the whole number into thirds:
37.3 *(1/3) =(approx) 12.43
now find 1/4 of that number:
12.43/4 = (approx) 3.1
oops… yeah E…gotta remember to do the whole problem…
E
1/4 * (1/2 * (1/3 * 37.3)) ~=1.6
E
1/6(37.3) = 4*x
x=1/24(37.3)
x=1.5541
x~1.6
I really don’t get the sense in post an answer without an explanation.
