Question

Shaunda answered 86% of the questions on her test correctly. If there were 50 questions on the test, how many did she NOT answer correctly?
pls help

Answer 1

Answer: 7 Answers Incorrect

Step-by-step explanation:

86% may be written as (86/100) or as 0.86.

Since "it's a ratio (sic.) problem," then:

                 86/100 = correct/50

                correct = (86/100)*50       (multiply both sides by 50)

                correct = 43

And, 50-43 = 7 incorrect

Answer 2
