1045/288


a/b = 51/54 --->(1)
b/c = 29/32 --->(2)
c/d = 440/493 --->(3)
e/f = 493/608 --->(4)
d/e = 38/55 --->(5)
(abc/def)*17=x


(1)* (2)* (3)=a/d---> (6)
(2)* (3)* (5)=b/e---> (7)
(3)* (4)* (5)=c/f---> (8)
(6)* (7)* (8)=abc/def ==> x=17*51/54*29/32*29/32*440/493*440/493*440/493*493/608 *38/55*38/55=1045/288=3.63
x=1045/288 or 3.63
