If `A:B = 2:1` and `A:C=1:3`, then `A:B:C` ?

If A:B = 3:5 and B:C = 2:3, then A:B:C is equal to: यदि A:B = 3:5 तथा B:C = 2:3 है, तो A:B:C का मान क्या होगा ?

If A:B=2:3 and B:C=4:17, then find A:B:C

A:C=2:3 and B:C=2:1 then find A:B:C

If A:B=4:5 and A:C=2:3, then what is (A+B):(B+C)=?

If A:B=4:9 and A:C=2:3 , find B:C and A:B:C

If A:B=3:4 and B:C=8:9 , then A:C is :  (a) 1:3   (b) 3:2,  (c) 2:3

If a:b=4:5 and b:c=2:3, then a:c=

If A:B=1/2:1/3, B:C=1/5:1/3 then (A+B):(B+C)=
