Question

a:b= 2.3,b:c=4:3,c:d=2.5anli a:d=?
​

Answer 1

Step-by-step explanation:

Given that :-

a:b=2:3

=>a/b=2/3 -----(1)

b:c=4:3

=>b/c=4/3 -----(2)

c:d=2:5

=>c/d=2/5 -----(3)

From (1),(2)&(3)

a/d=(a/b)×(b/c)×(c/d)

=>a/d=(2/3)×(4/3)×(2/5)

=>a/d=16/45

=>a:d=16:45

The value of a:d=16:45
