To compare Gracie's grade of 150200 with Lizzie's grade of 92%, we need to interpret what Gracie's score means in terms of a percentage.
Assuming that the total score possible for the assignment is 200, we can calculate Gracie's percentage as follows:
\[ \text{Gracie's Percentage} = \left( \frac{\text{Gracie's Score}}{\text{Total Possible Score}} \right) \times 100 \]
Plugging in the numbers:
\[ \text{Gracie's Percentage} = \left( \frac{150200}{200} \right) \times 100 = 750100% \]
Now we can compare the two percentages:
- Gracie's percentage: 750100%
- Lizzie's percentage: 92%
Clearly, Gracie's grade is much higher than Lizzie's grade.
