Explanation:
 First, you need to convert 16% to decimal form. To do this, you must divide it by 100. Then, the numerator will be 16 and the denominator will be 100:
 

 And finally, you need to simplify the fraction by reducing it. Notice that the numerator and the denominator can be both divided by 4. Then, dividing by 4 you get:
 

 Since the numerator and the denominator cannot be divided by the same number anymore, then the fraction is simplified.
 Therefore, the fraction equal to 16% (simplified) is:
