<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
Given Monique prefers the ratio of multiple-choice questions to essay questions to be 4:1, Therefore, we can write,
Multiple choice questions/ essay questions = 4/1,
If we multiply both the numerator and the denominator by 6, the ratio will be,
Multiple choice questions/ essay questions = 4/1 × 1
Multiple choice questions/ essay questions = (4/1) × (6/6)
Multiple choice questions/ essay questions = 24 / 6
Thus, Monique should choose the third option.
