3. Basir took a science test on Friday. One-eighth of the questions were multiple choice, and \( \frac{3}{4} \) of the questions were true-false questions. What part of the total number of questions were either multiple choice or true-false questions?

Let's break down the problem. If one-eighth of the questions were multiple choice, that's \( \frac{1}{8} \). The true-false questions make up \( \frac{3}{4} \) or \( \frac{6}{8} \) when converted to eighths. Now, add these two fractions together: \[ \frac{1}{8} + \frac{6}{8} = \frac{7}{8} \] So, \( \frac{7}{8} \) of the total number of questions were either multiple choice or true-false questions. To confirm this, let’s consider what this means: with just one-eighth for multiple choice and a whopping three-quarters for true-false, you almost have the entire test covered! Only one-eighth of the questions are left for other types.
