Gwen scored 24 marks correct out of 40 questions in her mathematics quiz. Express her score as a percentage?

To express Gwen's score as a percentage, we need to divide the number of correct answers by the total number of questions and then multiply by 100.

Percentage score = (24/40) x 100
Percentage score = 0.6 x 100
Percentage score = 60%

Therefore, Gwen scored 60% in her mathematics quiz.

To express Gwen's score as a percentage, we need to divide the number of marks she scored by the total number of questions and then multiply the result by 100.

Percentage = (Marks Scored / Total Questions) - 100

= (24 / 40) - 100
= 0.6 - 100
= 60%

Therefore, Gwen's score is 60%.
