To convert an interest rate to a percentage, you simply multiply the interest rate by 100. Here's the mathematical conversion:

Percentage = Interest Rate * 100

For example, if the interest rate is 0.05 (or 5%), you would multiply it by 100 to convert it to a percentage:

Percentage = 0.05 * 100
Percentage = 5%

So, the interest rate of 0.05 can be expressed as 5% when converted to a percentage.
