To calculate the percentage of marks Anna scored, you can use the formula:
\[
\text{Percentage} = \left( \frac{\text{Obtained Marks}}{\text{Total Marks}} \right) \times 100
\]
In Anna's case, she obtained 27 marks out of a total of 45 marks. Plugging in these values:
\[
\text{Percentage} = \left( \frac{27}{45} \right) \times 100
\]
Now, calculate the fraction:
\[
\frac{27}{45} = 0.6
\]
Now, multiply by 100 to get the percentage:
\[
0.6 \times 100 = 60
\]
So, Anna scored **60%** on her mathematics test.
