Question

What is \[\dfrac{1}{5}\] of \[20\]?

Answer 1

Hint: In order to determine the value \[\dfrac{1}{5}\] of \[20\]. The number above the fraction line is known as the numerator, and the number below it is known as the denominator.
To find the fraction of any number, we must first transform the whole number into a fraction.
The given question is to solve the fraction questions where the value is given as a fraction and needs to be converted into a whole number.

Complete step by step solution:
We have to find \[\dfrac{1}{5}\] of \[20\] as follows
Here's a piece of advice for you. If you use \[1\] as the denominator, you can convert any number to a fraction:
\[\dfrac{{20}}{1}\]
So, now that we've converted \[20\] to a fraction, we can multiply the two fractions by putting the fraction \[\dfrac{1}{5}\] next to our new fraction, \[\dfrac{{20}}{1}\].
All you have to do now is convert the entire number to a fraction and multiply the numerators and denominators. Let's take a look at some examples:
\[\dfrac{{1 \times 20}}{{5 \times 1}} = \dfrac{{20}}{5}\]
Our new fraction can be simplified even more in this case. To do so, we must find the greatest common factor between the two numbers.
If you want to do it yourself, you can use a handy GCF calculator. And the GCF of \[20\] and \[5\] equals \[5\].
To reduce this fraction to its simplest terms, divide both the new numerator and the denominator by \[5\].
\[\dfrac{{20}}{5} = 4\]
Since \[\dfrac{5}{5} = 1\]
When we bring it all together, we have the following full answer:
\[\dfrac{4}{1} = 4\]
Hence, the required solution \[4\] is \[\dfrac{1}{5}\] of \[20\].
