Question

What is the fraction \[\dfrac{1}{5}\] as percent?

Answer 1

Hint: A fraction represents a ratio. It has two parts, one is called the numerator and the other one is called the denominator. These two are divided by a small line. If the number is in fraction, then you need to convert it first into a whole or decimal number and then you have to convert it from the whole or decimal number into a percentage.

Complete step by step answer:
So, according to the question, Let’s first change the fraction \[\dfrac{1}{5}\] into a decimal or whole number. For converting it into a decimal number you need to divide the numerator by the denominator which is: \[1\,divided\,by\,5\,or\,\dfrac{1}{5}\] .

As we all know that \[\dfrac{1}{5}\,is\,also\,1 \div 5\] and it results in \[0.2\] where \[0.2\] is a decimal number.Now, you will convert the number from decimal number into a percent number. This can be done by multiplying the number to \[100\% \]. Instead of that you can also move two places forward of the decimal point. This will also give you the same result as \[20\% \].

Note: The above method was very simple and accurate but we have another method in which you need to multiply the numerator first by \[100\% \] . So, \[1\,\, \times \,\,100\% \] is \[100\% \] . Then you have to divide the resulting numerator by the denominator which is \[100\% \, \div \,5\] that gives you the result as \[20\% \].A percentage is also a ratio which can be expressed as a fraction of \[100\] . So, we can also say that the percentage means, a part per hundred.
