In a quiz with 20 questions you get 3 incorrect answers. What is your percent grade for the quiz? First - how many answers were correct? 20 - 3 = 17 Now write a ratio 17 20

17 x 5 20 x 5 85 Since 20 x 5 = 100 we multiply both numerator & denominator by 5 Then simplify 100 Writing 85% as a percent

85 100 = 85% Or ? as a decimal?
