Question

How do you write $2.43$ as a percentage?

Answer 1

Hint: For converting a given number into percentage, we multiply the given number by one hundred. For example, if we have the number $0.5$ which is supposed to be converted into the percentage, we multiply it by one hundred to get the percentage as $0.5\times 100=50\%$. So similarly, we need to multiply the number given in the above question, which is $2.43$, by one hundred to write it as a percentage.

Complete step by step answer:
Let the number given in the above question, which is equal to $2.43$, be equated to some variable, say $N$ so that we can write the below equation.
$\Rightarrow N=2.43$
Now, we know that for writing a given number as a percentage, we have to multiply the given number by one hundred. So we multiply the both sides of the above equation by one hundred to get
$\begin{align}
& \Rightarrow 100N=2.43\times 100 \\
& \Rightarrow 100N=243 \\
\end{align}$
So the number, after being multiplied by one hundred, comes out to be equal to $243$. Therefore, the given number $2.43$ is written as a percentage as $243\%$.

Hence, the final answer of the given question is $243\%$.

Note: Do not forget to attach the percentage symbol at the end, after multiplying the number with one hundred. Also, do not get confused by thinking that the percentage value must be less than hundred. In many of the daily applications it is so. But in some cases it can be greater than a hundred also.
