(a)/(b) = (4)/(3) , (b)/(d)= (8)/(9) , (c)/(d)= (2)/(5)
then what is (a)/(c)
+130514 (a)/(b) = (4)/(3) , (b)/(d)= (8)/(9) , (c)/(d)= (2)/(5)
then what is (a)/(c)
From the first ratio, b = (3/4)a
From the third ratio, d = (5/2)c ....so.......
Subbing into the second one
[(3/4)a] / [(5/2)c] = 8/9
(3/4) ( 2/5) [a / c] = 8/9
6/20 [ a / c] = 8/9
3/10 [a / c] = 8/9
a/c = 8/9 * 10/3 = 80/27
