Answer

 

The answer for 21 as a percentage is 2100%.

 

Explanation

 

Converting a number to a percentage is a simple task that can be done in a few steps. Follow these steps to find the answer.

 

Step 1: To convert a number to a percentage, we start by expressing the number as a fraction of 100. Here, 21 is the number, and we need to express it as a fraction with 100 as the denominator. Thus, 21 becomes 21/1.

 

Step 2: Since we are converting to a percentage, we multiply both the numerator and the denominator by 100 to convert the fraction to a percentage. 21/1 × 100/100 = 2100/100

 

Step 3: The fraction 2100/100 simplifies to 2100 when expressed as a percentage, because the denominator is 100.

 

Therefore, 21 can be written as 2100% when expressed as a percentage.
