To find the percentage of questions that Isabella got right, you can use the formula:
\[
\text{Percentage} = \left( \frac{\text{Number of correct answers}}{\text{Total number of questions}} \right) \times 100
\]
In Isabella's case:
\[
\text{Percentage} = \left( \frac{107}{637} \right) \times 100
\]
Calculating the fraction:
\[
\frac{107}{637} \approx 0.167
\]
Now, multiplying by 100 to get the percentage:
\[
0.167 \times 100 \approx 16.67
\]
Therefore, the decimal representation rounded to two digits after the decimal point is:
\[
16.67
\]
