To find out what percent of 25 is 50, you can use the formula:
\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \]
In this case, the "part" is 50 and the "whole" is 25. Plugging in the numbers:
\[ \text{Percentage} = \left( \frac{50}{25} \right) \times 100 = 2 \times 100 = 200% \]
So, 50 is 200% of 25.
