Riley answered 42 questions correctly on her multiple choice science final and earned a grade of \( 35 \% \). Ho many total questions were on the final exam?

To find the total number of questions on the final exam, you can use the formula for calculating a percentage. If Riley answered 42 questions correctly and that represented 35% of the total questions, you can set up the equation: \( \frac{42}{x} = 0.35 \) Where \( x \) is the total number of questions. To solve for \( x \), multiply both sides by \( x \) and then by 100: \( 42 = 0.35x \) Now divide both sides by 0.35 to isolate \( x \): \( x = \frac{42}{0.35} = 120 \) So, there were a total of 120 questions on the final exam! In a similar context, students often rely heavily on multiple-choice formats, finding strategies to excel. Understanding key concepts rather than memorizing answers can help improve scores significantly! Test-takers sometimes make the mistake of focusing too much on eliminating wrong answers rather than being confident in their first instinct. Trusting your gut can lead to better results!
