=0.25

To solve this problem, you can first set up a fraction to show how much is done out of the total amount of questions. Since there are 16 total questions, the denominator will be 16. Since 4 questions were answered, 4 is going to be the numerator. So, your fraction will be 4/16. 

4/16 can be simplified to 1/4

Divide 1 by 4 to get a decimal. The decimal that you get should be 0.25. Move the decimal point to the right 2 places to get what it is as a percent. 

0.25 = 25%
