Noah is taking an online survey. After answering 16 questions, he gets a message that he has completed 80% of the survey. Noah wants to know the total number of questions on the survey

Answer: 20 questions

Step-by-step explanation:

From the question, Noah is taking an online survey and after answering 16 questions, he gets a message that he has completed 80% of the survey.

To get the total number of questions in the survey goes thus:

Let the total number of questions be y.

80% of y = 16

80/100 * y = 16

0.8 * y = 16

0.8y = 16

Divide both side by 0.8

y = 16/0.8

y = 20

The survey has 20 questions.
