set it up like this:

10/x = 5/100 %

Cross multiply

100 * 10= 1000

1000/5=200
to find out a number when your given a number and what percent of that number it is you just want to divide the given number by percentage given then multiply by 100 so in this case it would be 

10/5 = 2 
2*100= 200 
so 10 is five percent of 200
