There are two main ways to express a fraction as a percentage:
- Divide 100 by the numerator, and then multiply both numerator and denominator by the answer.
- Convert the fraction to a decimal first, then multiply the answer by 100.
The first step is to make sure we understand all of the terms in the problem we are trying to solve:
- Numerator - this is the number above the fraction line. For 21376, the numerator is 21.
- Denominator - this is the number below the fraction line. For 21376, the denominator is 376.
- Per cent - "per cent" means parts per hundred, so saying 50%, for example, is the same as the fraction 50100 or 510.
Convert 21/376 to Percentage by Changing Denominator
The first method we have is to convert the fraction so that the denominator is 100. Since "per cent" means parts per hundred, if we can convert the fraction to have 100 as the denominator, we then know that the top number, the numerator, is the percentage.
First, we divide 100 by the denominator:
Once we have the answer of 0.26595744680851, we can multiply both the numerator and the denominator by it to get our new "percent" fraction:
Our percent fraction is 5.5851063829787/100, which means that 21376 as a percentage is 5.59%.
Convert 21/376 to Percentage by Converting to Decimal
With this method, we first need to divide the numerator by the denominator:
Once we have the fraction in a decimal format, the answer is then multiplied by 100 to get the correct percentage:
We can see that this gives us the exact same answer as the first method: 21/376 as a percentage is 5.59%.
Both methods of converting a fraction to a percentage are pretty straightward and can be applied to any fraction easily when you have learned and memorized the steps involved.
Note, the final percentage is rounded to 2 decimal places to make the answer simple to read and understand.
