I went from the square root of (29/100) to the square root of 29 divided by the square root of 100. Since the square root of 100 is 10, I was able to take the square root sign out of the denominator. However, since 29 is not a perfect square, I had to leave the square root sign in the numerator. I don't know the square root of 29 off the top of my head and it's certainly not 5.5
5.5 was an approximation because I know it's between 5 and 6
