To compare Gracie's grade to Lizzie's grade, we'll convert Gracie's score of \( \frac{150}{200} \) into a percentage.
- Calculate Gracie's percentage: \[ \frac{150}{200} = 0.75 \] To convert to percentage: \[ 0.75 \times 100 = 75% \]
Gracie earned 75%.
- Lizzie earned 92%.
Now comparing the two percentages:
- Gracie: 75%
- Lizzie: 92%
Lizzie has the higher grade. Therefore, the answer is:
92%
