Question

How do you convert $\dfrac{1}{5}$ into a decimal and percent?

Answer 1

Hint: In this question we have been asked to convert the given number $\dfrac{1}{5}$ into decimal and percent. For converting into decimal we will multiply the numerator and denominator with 2 and for converting into percent we will multiply the whole fraction with 100.

Complete step by step solution:
Now considering from the question we have been asked to convert the given number $\dfrac{1}{5}$ into decimal and percent.
For converting into decimal we will multiply the numerator and denominator with 2.
By performing this arithmetic operation on the given fraction we will have $ \dfrac{1\times 2}{5\times 2}=\dfrac{2}{10}=0.2$ .
Hence, $\dfrac{1}{5}$ can be expressed as 0.2 in decimal.
For converting into percent we will multiply the whole fraction with 100.
By performing this arithmetic operation on the given fraction we will have $ \dfrac{1}{5}\times 100=20\%$
Hence, $\dfrac{1}{5}$ can be expressed as 20% in decimal.
Therefore we can conclude that the given number $\dfrac{1}{5}$ can be expressed as 0.2 in decimals and 20% in percent.

Note: This is a very easy and simple question and can be answered accurately in a short span of time. Very few mistakes are possible in this type of question. During the process of answering questions of this type we should carefully perform the calculations. For example if we had calculated wrongly during decimal conversion and written it as $ \dfrac{1\times 2}{5\times 2}=\dfrac{2}{100}=0.02$ which is a wrong answer clearly.
