How do I figure out the answer to this ? It's been a while since I came across one like it; On a test, 6.25% of the questions are answered incorrectly. If 5 questions are answered incorrectly, how many questions are on the test ?

0.0625x = 5

x = 5 / 0.0625

x = 80

To determine the number of questions on the test, you can use the concept of percentages and proportions.

Step 1: Determine the percentage of questions that are answered incorrectly.
In this case, it is given that 6.25% of the questions are answered incorrectly.

Step 2: Convert the percentage to a decimal.
To do this, divide the percentage by 100.
6.25% รท 100 = 0.0625

Step 3: Set up a proportion to find the total number of questions.
Let x represent the total number of questions on the test. Since 6.25% (or 0.0625) of the questions are answered incorrectly, you can write the proportion:
0.0625 (incorrectly answered questions) / 1 (total questions on the test) = 5 (number of questions answered incorrectly) / x (total number of questions)

Step 4: Solve the proportion for x.
Cross-multiply by multiplying 0.0625 and x.
0.0625 * x = 5

Step 5: Divide both sides of the equation by 0.0625 to solve for x.
x = 5 / 0.0625

Step 6: Calculate the value of x.
Divide 5 by 0.0625 to find x.
x = 80

Therefore, there are 80 questions on the test.
