Answer:

$\huge{\boxed{\rm{\red{a:d=16:45}}}}$

Step-by-step explanation:

Given :-

a:b=2:3, b:c=4:3, c:d=2:5

To find:-

Find a:d

Solution:-

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)

now a/d can be written as

a/d=(a/b)×(b/c)×(c/d)

=>a/d=(2/3)×(4/3)×(2/5)

=>a/d=(2×4×2)/(3×3×5)

=>a/d=16/45

a:d=16:45

Answer:-

a:d=16:45
