A test has 20 questions. If Jeri gets 80 percent correct, how many questions did she miss?
Answer 4
Start by determining the percentage of correct answers Jeri made, so 80 percent of 20 or 80/100 × 20 = 0.80 × 20 = 16. Sixteen is the percentage, or what you get when you take the percent of a number. Now that we know how many questions Jeri got correct - 16 - we can figure out how many she missed: 20 − 16 = 4
