The question in the image is asking what percentage "5 out of 20" is equivalent to. Here's how we can calculate it:

The formula to calculate a percentage is: $\text{Percentage} = \left(\frac{\text{part}}{\text{whole}}\right) \times 100$

In this case, the part is 5, and the whole is 20: $\text{Percentage} = \left(\frac{5}{20}\right) \times 100 = 25\%$

So, 5 out of 20 is equivalent to 25%.
