1. Find Sub-Duplicate ratio of `16:25`

Solution:
For ratio `a:b`, `sqrt(a):sqrt(b)` is called sub duplicate ratio.


`:.` sub duplicate ratio of `16 : 25` is `sqrt(16) : sqrt(25) = 4:5`


2. Find Sub-Duplicate ratio of `9:49`

Solution:
For ratio `a:b`, `sqrt(a):sqrt(b)` is called sub duplicate ratio.


`:.` sub duplicate ratio of `9 : 49` is `sqrt(9) : sqrt(49) = 3:7`
