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

7 questions were wrong

Answer 2

Answer: 7 Answers Incorrect

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
