Question

a:b=2:3
b:c=6:9
c:d=5:7
a:d=?

Answer 1

Answer:

Solution :-

a : b = 2 : 3

b : c = 6 : 9

c : d = 5 : 7

a : d = ?

We can write as :

a : b = 2 : 3

= a/b = 2/3

again,

b : c = 6 : 9

= b/c = 6/9

and,

c : d = 5 : 7

= c/d = 5/7

➜ a/b × b/c × c/d = 2/3 × 6/9 × 5/7

➜ a/d = 60/189

➜ a/d = 20/63

∴ a : d = 20 : 63
