What is 5.5 percent in decimal form?

"percent" means" out of 100", so 5.5 % is 5.5/100. To change this "fraction" to a decimal divide the numerator (5.5) by the denominator (100). The easiest way to do this is to move the decimal two places to the left. So in this case, if you move the decimal two places to the left from 5.5%, you have 0.055.
