In a test for every 6 answers carlene got correct, she got 2 wrong. She got 54 correct answers.
1 how many questions did the test have?
2 express the number of questions she answered correct as a percentage.

1. 0
2. 0
3. 24
1. ratio of correct to wrong = 6 : 2 = 3 : 1
= 3x : x

total questions = 4x
given: 3x = 54
x = 18
so there were 4(18) or 72 questions

percentage correct = 54/72
= .75 or 75%

we could have seen that from the top
correct = 3x, total = 4x
percentage correct = 3x/4x = 3/4 = .75
