To determine if Emily achieved Grade A in math, we need to calculate the percentage of questions she got correct.
1. Emily got 45 questions correct out of a total of 60 questions.
2. To find her percentage, we use the formula:
\[
\text{Percentage} = \left( \frac{\text{Correct answers}}{\text{Total questions}} \right) \times 100
\]
Plugging in the numbers:
\[
\text{Percentage} = \left( \frac{45}{60} \right) \times 100
\]
3. First, calculate \( \frac{45}{60} \):
\[
\frac{45}{60} = 0.75
\]
4. Now, multiply by 100 to get the percentage:
\[
0.75 \times 100 = 75\%
\]
Now, we compare this to the 80% requirement:
- Since 75% < 80%, Emily does not meet the requirement for Grade A.
In conclusion, Emily's percentage on the final test is **75%**, and her answer should be:
**No, 75%**.
