The question that is asked is pretty straight forward. Only thing that needs to be found is the number of 30 in the number 600. By dividing 600 by 30 we can arrive at the desired result. 
Number of 30 in 600 = 600/30
                                 = 60/3
                                 = 20
So there are 20 number of 30s in the number 600. This method can be used to find answers to several other similar kind of questions like the number of 10s in 1000.Following the same procedure we get
Number of 10 in 1000 = 1000/10
                                   = 100

Answer: Technically, it would be 9/3, but you can simplify that to 3.
 
        
                    
             
        
        
        
To calculate the square root, you can either use the √symbol on a calculator or you can manually find it using Prime Factorization. For non-perfect squares, Prime Factorization is the way to go. 
 The first two steps work for solving large perfect squares as well.
1. Divide your number into perfect square factors.
2. Take the square roots of your perfect square factors. 
3. If your number doesn't factor perfectly, reduce your answer to simplest terms. 
4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be. 
ie.  

       you know that 

 and 

,  so you can estimate that the 

 would be between 7 and 8 but closer to 8.
5. <span>Alternatively, reduce your number to its lowest common factors as your first step.</span><span> Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).
ie.  </span>
