Question

How do you write \[\dfrac{2}{5}\]as a percent\[?\]

Answer 1

Hint:
The given question is to convert the given question into percent for the conversion of the fraction to percentage. The rule for that is to multiply the given fraction with \[100\] and Hence the number obtained is the equivalent percentage of the given fraction.

Complete Step by step Solution:
 In the question,\[,\]we had asked to convert the given fractional number in the percentage fractional number that can be written as a rational number where the proper fraction and the improper fraction are the two types of a proper fraction. The given question is to convert the given fraction into the percentage.
The formula or rule to convert decimal or fraction into a percent is that we have to multiply the given number in decimal or fraction with \[100\] and hence the number obtained is the percentage equivalent to the number in decimal as well as in the fraction either it is a proper fraction or improper fraction. Now the question is to convert \[\dfrac{2}{5}\] into percent which means we have to convert fraction to a percentage. Therefore the fraction is to be converted to percent.
So, \[\dfrac{5}{2}\] is to be converted to a percentage.
For this, we have to multiply \[\dfrac{5}{2}\]by\[100\] which is the rule to convert fraction to percent. So we get
\[\dfrac{5}{2} \times 100\% \]
which becomes \[\dfrac{{500}}{2}\% \]
and when \[500\]is divided by \[2,\]
we are left with \[250\% \]

Therefore \[2.5\] is equal to \[\dfrac{5}{2}\] in fraction and equivalent to \[250\% \]

Note:
The given question was to convert the given number in fraction to the percent. The rule for this conversation is that to multiply the given number in fraction by \[100.\]If the number is in decimal \[,\]then the conversion for any type of number to percentage \[,\]we have to multiply the number in decimal or in fraction with \[100.\]
