On which quiz did Kelly get more questions correct?

Answer 1

She had more correct answers on the first quiz

Step-by-step explanation:

1- For the first quiz:

We know that the quiz had a total of 15 questions and that Kelly had
`(4)/(5)` of those correct

This means that:

Number of correct answers =
`(4)/(5)*15 = 12` answers

2- For the second quiz:

We know that the quiz had a total of 12 questions and that Kelly had
`(5)/(6)` of those correct

This means that:

Number of correct answers =
`(5)/(6)*12=10` answers

3- Comparing the number of correct answers:

From the above calculations, we know that she had 12 correct answers on the first quiz and 10 on the second

This means that she had more correct answers on the first quiz

Hope this helps :)
