Answer:
1:2
Step-by-step explanation:
There are 5 square numbers and 10 prime numbers between 1 and 30 so this is what you will do:
1:Since you said square numbers to prime numbers, you start with the total number of square numbers which is 5
2:Then you put a colon and put the total number of prime numbers which is 10 after it ,which the answer will be 5:10
3:Now you have to simplify it, since 5 can go into itself and 10, the answer will be 1:2
Therefore, it will be 1:2
