To determine if Mrs. Lynch would pass with 25 out of 30 questions correct, we first need to calculate her score as a percentage and compare it to the passing grade of 0.85.
1. **Calculate the score for 25 out of 30 questions:**
\[
\text{Score} = \frac{\text{Correct Answers}}{\text{Total Questions}} = \frac{25}{30}
\]
2. **Convert the fraction to a decimal:**
\[
\frac{25}{30} = \frac{5}{6} \approx 0.8333
\]
3. **Compare the score against the passing grade:**
The passing grade is 0.85 (or 85%). Since 0.8333 is less than 0.85, Mrs. Lynch would not pass if she got 25 out of 30 questions correct.
Therefore, Mrs. Lynch would not pass with 25 out of 30 correct answers.
