# Rate per 100 Calculator

## How to calculate rate per 100?

The formula to calculate the rate per 100 (\(R_{100}\)) given the part (\(P\)) and the whole (\(W\)) is:

\[ R_{100} = \left( \frac{P}{W} \right) \times 100 \]Where:

- \(R_{100}\): Rate per 100
- \(P\): Part
- \(W\): Whole

Find the rate per 100 (\(R_{100}\)) for a part of \(25\) out of a whole of \(50\).

**Answer:**

Using the rate per 100 formula:

\[ R_{100} = \left( \frac{25}{50} \right) \times 100 = 50\% \]Therefore, the rate per 100 is \(50\%\).
