Isabella got 107 out of 637 questions right on her math pre-test, what percentage did she get right? Write the decimal and only the two digits after the decimal point.

Answer 1

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:

\[ 16.67 \]
