Question

Bradley answered 80% of the question on his science test correctly. There were 30 questions on the test, and all the questions were equal value. How many questions did bradley NOT answer correctly

Answer 1

6

Answer 2

percent means per 100
80% correct means 100-80 = 20% incorrect
total is 30
20% of 30 = (20/100)(30)

Answer 3

if she answers 80% correctly... the remaining 20% is the amount that she failed to answer correctly ...
so find 20% of 30

(20/100) x 30 = 6%

Answer 4

@***[ISURU]*** not % just 6 the amount of questions incorrect
