# If a : E = 5 : 12, E : I = 8 : 3 and I : U = 9 : 16, Then Llnd a : U - ICSE Class 10 - Mathematics

#### Question

If a : e = 5 : 12, e : i = 8 : 3 and i : u = 9 : 16, then find a : u

#### Solution

a : e = 5 : 12 => "a"/"e" = 5/12

e : i = 8 : 3 => "e"/"i" = 8/3

i : u = 9 : 16 => "i"/"u" = 9/16

=> "a"/"e" xx "e"/"i" xx "i"/"u" = 5/12 xx 8/3 xx 9/16

=> "a"/"u" = 10/6 = 5/8

a : u = 5 : 8

Is there an error in this question or solution?
