Anna scored 27 marks out of the possible 45 mathematics test.what percentage was this?

Answer 1

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.
