If `A:B=2:3, 7B=9C and 15C=14D` then find `A:D`

If A:B=2:3,7B=9C and 15C=14D then there is A:D

(2) If A:B=2:3 , B:C=4:5 and C:D=6:7, find A:D

If A:B= 2:3,B:C = 4:5 and C : D=5 :9, then A: D is equal to- यदि A:B= 2:3,B:C = 4:5 और C : D=5 :9 हो, तो A: D बराबर होगा?

If A:B=3:4,B:C=5:7 and C:D=8:9 then A:D is equal to

If A:B=2:3 , B:C = 4:5, C:D = 6:7. then A : B : C : D is-

If A:B=3:4, B:C=8:9, C:D=15:16 then A:D is equal to ?

In a Delta ABC, I is the incentre and AI cuts BC at D. If B=(-1,2) C(9,7), AB = 14, AC =21 then find D.
