Hi

The answer is 15: 8

This is because,

We have,

A: B = 2: 3

Or A/B = 2/3

And ,

B: C = 4: 5

Or B/C = 4/5

Now,

A/C

= (A/B) × (B/C)

= (2/3) × (4/5)

= (8/15).........,. 1

Then,

C:A

=C/A

= 1/ ( A/C)

= 1 ( 8/15) ..... Using 1

= 15/8

= 15 :8

Hence, C:A = 15:8

I hope that you find this helpful

Thank you
